Effective lining quality detection and evaluation is beneficial to accurately judging the quality of concrete structures, guiding the regulation and maintenance of lining diseases and ensuring the operation safety of tunnels.

Fig. 1 is a step diagram of a method for analyzing tunnel lining quality according to an embodiment of the present application. As shown in fig. 1, a method for analyzing quality of a tunnel lining (hereinafter, referred to as "lining quality analyzing method") according to an embodiment of the present invention includes the steps of: step S110, collecting internal and apparent detection data of the lining and calibrating lining states at different positions; step S120, performing cause analysis on the defects inside and outside the lining and determining the quality degradation level; step S130, performing correlation analysis on the internal and external defect combinations according to the internal and external states and causes of the lining; step S140, fusing data characteristics obtained from the two types of analysis results of the step S130 and the step S140 by adopting a data fusion technology according to the internal and apparent detection data of the lining under different lining conditions, and constructing a tunnel lining quality diagnosis model; and S150, evaluating the quality of the target lining by applying a tunnel lining quality diagnosis model.
Fig. 2 is an overall technical roadmap of the method for analyzing tunnel lining quality according to the embodiment of the present application. A specific flow of the lining quality analysis method according to the embodiment of the present invention will be described with reference to fig. 1 and fig. 2.
In step S110, first, the internal lining detection data and the apparent lining detection data at different positions need to be collected, and then, the corresponding lining states are calibrated in the internal lining at different positions and the corresponding lining states are calibrated in the apparent lining at different positions, so as to finally form a tunnel lining defect large data set.
Fig. 3 is a flowchart of a preparation process of a tunnel lining defect database in the method for analyzing tunnel lining quality according to the embodiment of the present application. As shown in fig. 3, the process of collecting the internal and apparent defect data of the lining includes: firstly, a construction site needs to be determined for a data acquisition field test, so that corresponding detection and data processing modes are determined according to two aspects of internal defects and apparent defects of the lining according to the field condition of a selected work point. Specifically, the method comprises the steps of firstly collecting lining internal detection data at different positions and lining apparent detection data at different positions, then preprocessing the lining internal detection data at different positions and the lining apparent detection data at different positions, and calibrating the lining state at the corresponding positions according to the preprocessed lining internal detection data and the preprocessed lining apparent detection data, so that the interpretation of the internal and external defects of the lining at different positions is completed. Wherein the lining conditions include, but are not limited to: defect type, defect development scale, and defect boundaries. Defect types include, but are not limited to: voids, lack of compaction, lack of thickness, cracks and water leakage.
Further, in the embodiment of the invention, geological radar technology and/or ultrasonic detection technology are adopted to collect the internal detection data of the lining at different positions. In addition, the apparent detection data of the lining at different positions are collected by adopting image shooting and/or three-dimensional laser scanning technology.
In a first preprocessing example, the lining interior detection data collected by geological radar technology is preprocessed, including gain, filtering, deconvolution, statics, and offset.
In the second preprocessing example, preprocessing including distortion correction, image enhancement, resolution adjustment, and threshold segmentation is performed on an apparent image acquired by image capturing.
Therefore, in step S110 of the invention, based on a large number of tunnel lining quality detection engineering practices and field tests, a lining internal defect data set is obtained by means of ground penetrating radar and other technologies, a tunnel lining apparent defect data set is obtained by means of apparent shooting and other technologies, the property states such as the type and scale of lining defects are calibrated according to manual interpretation, expert judgment and other modes, the collection and preparation of a tunnel lining defect big data set are completed, and then the step S120 is carried out.
Step S120, firstly, according to the detection data of the interior of the lining at each position and the lining defect state corresponding to the detection data, performing cause analysis on the interior defects of the lining at different positions, determining the quality degradation level of the interior of the lining at each position, and according to the detection data of the appearance of the lining at each position and the lining defect state corresponding to the detection data, performing cause analysis on the appearance defects of the lining at different positions, and determining the quality degradation level of the appearance of the lining at each position.
Further, in the process of analyzing the cause of the internal defects and the apparent defects of the lining at different positions, firstly, the internal defect types and the external defect types of the lining at different positions are classified in a grading way according to the internal and apparent detection data of the lining and the corresponding lining state, so that the internal and external defect types and the defect grades of the lining at different positions are counted. Specifically, according to internal detection data and corresponding lining states of the lining at different positions collected in a tunnel lining defect big data set, and apparent detection data and corresponding lining states of the lining at different positions, the category grade of the internal defect of each position lining (the grade of the defect condition of the current position in the defect type) and the category grade of the apparent defect of each position lining are determined, and finally, according to different lining types, the spatial geometric distribution rule of each lining type is counted, namely, the distribution states of the internal lining and the external lining of each lining type at different positions of the tunnel and the spatial distribution state of category grade information of the lining type are determined.
After the analysis of the single defect distribution is completed, step S120 further needs to analyze the cause of the internal defect of the lining at different positions and the cause of the apparent (external) defect of the lining at different positions from the three causes of the construction quality type, the stress type and the degradation type, so as to further determine the quality degradation level of the internal defect of the lining at different positions and the quality degradation level of the external (apparent) defect of the lining at different positions according to the detection data of the internal and external defects of the lining at different positions, the lining state, the category level and the cause analysis result.
Specifically, according to theoretical analysis, practical experience and field investigation conditions, from the three aspects of construction quality type, stress type and degradation type, the cause influencing the internal lining state of the current position and the cause influencing the apparent lining state of the current position are analyzed according to the combination condition of the internal and external defect types of different positions, and the influence degree of the position on the structural state of the whole tunnel is determined to be classified into grades, namely the quality degradation grade inside the current position and the apparent quality degradation grade according to the single defect type and the cause of the internal defect and the apparent defect of the lining of different positions. Further, in determining the cause of the internal or apparent lining state at each position, one selected from construction quality, stress, and deterioration is selected.
Accordingly, after the single-type cause analysis of the defect of the tunnel lining is performed, the process proceeds to step S130.
