Description
Technical Field
The invention relates to the technical field of a structural surface manufacturing die and a test of a direct shear test, in particular to an integrated device for manufacturing a structural surface with a weak interlayer and testing the direct shear.
Background
The structure has a controllable influence on the stability of the rock mass in engineering, in particular to a weak structure surface containing a weak interlayer. The weak structural surface is a weak band with a certain thickness in the rock mass, has the characteristics of high compression, low strength and the like compared with the rock mass at two adjacent sides, and generally controls the deformation and stability of the rock mass. In practical engineering projects, accidents frequently occur due to the existence of a weak interlayer, and serious life and property losses are caused, so that the research on the mechanical properties of the structural surface of the weak interlayer is particularly important.
The acquisition of rock mass structural plane samples containing weak interlayers generally has two means of field on-site sampling and indoor manufacturing. The original rock structural surface sample containing the weak interlayer is obtained in the field, and the following defects exist: 1) The weak interlayer is easy to disturb, and a primary rock structural surface sample containing the weak interlayer, which is consistent with the state of the present place, is difficult to obtain; 2) On site, a plurality of groups of samples with the properties approximately consistent with those of the original rock structural surface containing the weak interlayer are difficult to obtain, and structural surface mechanical indexes cannot be obtained through direct shear tests of the plurality of groups of samples; 3) The on-site sampling has the defects of high difficulty, high cost, long sampling period, high risk and the like. Therefore, indoor production is an important method for obtaining a sample of a rock mass structural plane containing a weak interlayer.
To obtain weak structural plane mechanical parameters, two steps are generally required: 1) Adopting a structural surface manufacturing mould containing a weak interlayer to manufacture a structural surface sample containing the weak interlayer; 2) And removing the structural surface manufacturing die, and placing the manufactured structural surface sample containing the soft interlayer into a corresponding shearing box for direct shearing test. The mechanical parameters of the structural surface containing the weak interlayer can be obtained only by the two steps of the structural surface manufacturing die and the two shearing boxes matched with the direct shearing test, so that the process is complex, the cost is high, and the testing period is long.
