Description

一种基于三维GIS的岩土工程BIM应用***A BIM application system for geotechnical engineering based on 3D GIS 技术领域Technical Field
本发明涉及地理信息技术领域，具体的说是以“BIM+GIS”集成技术为基础，以多源异构数据可视化集成、定量化分析、协同化应用和数字化管理为目标，形成集地上、地表、地下岩土工程多源数据的三维可视化集成展示、岩土工程定量化分析评价、勘察设计多专业跨阶段协同化应用和数据成果数字化交付与管理功能于一体的应用***，有利于提高勘察设计企业在岩土工程多专业一体化领域技术咨询的数字化水平，有利于提高政府和行业对城市地下空间开发、建设与运维的管理水平；的一种基于三维GIS的岩土工程BIM应用***。The present invention relates to the field of geographic information technology, and specifically to a "BIM+GIS" integrated technology as a basis, with the goal of visual integration, quantitative analysis, collaborative application and digital management of multi-source heterogeneous data, to form an application system that integrates three-dimensional visual integrated display of multi-source data of ground, surface and underground geotechnical engineering, quantitative analysis and evaluation of geotechnical engineering, cross-stage collaborative application of multiple disciplines in survey and design, and digital delivery and management of data results, which is conducive to improving the digital level of technical consultation of survey and design enterprises in the field of multi-discipline integration of geotechnical engineering, and is conducive to improving the management level of government and industry for the development, construction and operation and maintenance of urban underground space; a geotechnical engineering BIM application system based on three-dimensional GIS.
背景技术Background technique
随着IT技术和产业的迅速发展，地理信息***(GIS)以它显著的特点和日益强大的功能广泛地深入到各行各业，并在其中发挥着越来越重大的作用。与此同时，这些应用反过来又对GIS提出了更多、更高的要求。人们生活在一个真实的三维空间内，很多实际现象依靠现有的2D GIS得不到很好的解决，如城市规划中立交桥及建筑物的设计及景观模拟；地下铁路、商场、停车场及其它服务设施的数据管理及图形显示；电力、通讯设施的合理布局与规划；房产部门中楼房住宅的消防、供电、供水、供气、报警等设施的合理配置；城市地上、地下管网的合理分布、管理、查询及最佳路径的选择；航空飞行线路的规划与管理；地质、石油等领域的地层、断裂、地质构造体、油层、地下气、地下水等各种现象的描述及分析等等。这些都需要直观的真三维表示，传统的2D GIS已结不能满足人民的应用需求，它迫切需要向3D GIS转换。因此，3D GIS激起了研究人员的强烈兴趣。对3D GIS的研究已成为学术界关注的热点。With the rapid development of IT technology and industry, geographic information system (GIS) has penetrated into all walks of life with its remarkable characteristics and increasingly powerful functions, and has played an increasingly important role in them. At the same time, these applications have in turn put forward more and higher requirements for GIS. People live in a real three-dimensional space, and many practical phenomena cannot be well solved by existing 2D GIS, such as the design and landscape simulation of overpasses and buildings in urban planning; data management and graphic display of underground railways, shopping malls, parking lots and other service facilities; reasonable layout and planning of power and communication facilities; reasonable configuration of fire protection, power supply, water supply, gas supply, alarm and other facilities in building residences in real estate departments; reasonable distribution, management, query and selection of optimal paths for urban ground and underground pipelines; planning and management of aviation flight routes; description and analysis of various phenomena such as strata, faults, geological structures, oil layers, underground gas, groundwater, etc. in the fields of geology and petroleum, etc. All of these require intuitive true three-dimensional representation. Traditional 2D GIS can no longer meet people's application needs, and it urgently needs to be converted to 3D GIS. Therefore, 3D GIS has aroused strong interest among researchers. Research on 3D GIS has become a hot topic in the academic community.
随着“数字地球”、“数字城市”等一系列概念的提出，有关三维城市模型的应用需求正迅速增加。地理信息的普遍服务如数字城市、虚拟地理环境等也对其三维表示提出了紧迫的要求，而对地观测技术和计算机技术特别是分辨率遥感技术和计算机图形图像处理技术的进步为此提供了多种显示途径。地理信息的三维表示具有以下显著的特征：With the introduction of a series of concepts such as "digital earth" and "digital city", the application demand for three-dimensional city models is increasing rapidly. Universal services of geographic information such as digital cities and virtual geographic environments have also put forward urgent requirements for their three-dimensional representation, and the progress of earth observation technology, computer technology, especially high-resolution remote sensing technology and computer graphics and image processing technology has provided a variety of display methods for this. The three-dimensional representation of geographic information has the following significant features:
三维表示能够给与用户更加直观的空间高程信息，而传统的二维表示反映的都是空间物体的平面位置，其高程信息只是作为一个属性值而存在，并不能被直观地反映出来。Three-dimensional representation can provide users with more intuitive spatial elevation information, while traditional two-dimensional representation reflects the planar position of spatial objects, and its elevation information only exists as an attribute value and cannot be reflected intuitively.
以更加直观和逼真的方式指出空间目标种类及数量和质量特征以及对象的空间位置和现象的时空分布，所以三维表示具有完整的时空定位特征。The types, quantity and quality characteristics of spatial targets, as well as the spatial positions of objects and the spatiotemporal distribution of phenomena are pointed out in a more intuitive and realistic way, so the three-dimensional representation has complete spatiotemporal positioning characteristics.
与之对应，数码城市是关于城市的一种逼真的三维数字表示，使人们可以探 察汇集关于城市的自然和人文信息，并与之互动。在摄影测量界，数码城市大多数情况下指三维城市模型，它不仅呈现三维城市模型，而且还提供具有相片直观的表面描述如逼真的材质和纹理特征以及相关的属性信息，满足数码城市需要的GIS被称为“数码城市GIS”。与三维可视化和虚拟显示技术相比，实用化的真三维GIS的研究进展则缓慢很多，其理论与技术都还不成熟。因此，不像一般意义的真三维GIS，数码城市GIS现阶段还只是真三维GIS一种特殊的原型***，根据大多数的应用需求在许多方面进行了简化，比如采用外包围表面模型代替实体几何模型和淡化了复杂的空间拓扑关系等，不论现实世界如何映射到空间数据库，更强调GIS以一种稳健有效的方式提供三维能力。In contrast, the digital city is a realistic three-dimensional digital representation of the city, allowing people to explore Observe and collect natural and cultural information about the city and interact with it. In the field of photogrammetry, digital city refers to 3D city model in most cases. It not only presents 3D city model, but also provides photo-intuitive surface description, such as realistic material and texture features and related attribute information. GIS that meets the needs of digital city is called "digital city GIS". Compared with 3D visualization and virtual display technology, the research progress of practical true 3D GIS is much slower, and its theory and technology are not yet mature. Therefore, unlike the true 3D GIS in the general sense, digital city GIS is only a special prototype system of true 3D GIS at this stage. It has been simplified in many aspects according to most application requirements, such as using outer enclosing surface model instead of solid geometric model and downplaying complex spatial topological relationship. No matter how the real world is mapped to the spatial database, it emphasizes that GIS provides 3D capabilities in a robust and effective way.
但是目前的三维GIS***存在若干关键技术问题，如将BIM与GIS有效地进行结合后再以多源异构数据进行可视化集成、定量化分析、协同化应用和数字化管理，形成集地上、地表、地下岩土工程多源数据的三维可视化集成展示、岩土工程定量化分析评价、勘察设计多专业跨阶段协同化应用和数据成果数字化交付与管理功能于一体的应用***，有利于提高勘察设计企业在岩土工程多专业一体化领域技术咨询的数字化水平，有利于提高政府和行业对城市地下空间开发、建设与运维的管理水平。通过对多来源、多专业、多类型的岩土工程BIM数据和地理信息数据进行轻量化处理整合，获得空间数据库标准格式的BIM轻量化模型，并与对应属性信息进行关联挂接，得到数据完整的各专业BIM轻量化模型，对多源异构数据进行可视化集成，为岩土工程定量化分析、协同化应用和数字化统一管理提供数据基础。基于轻量化的工程地质模型，通过虚拟布桩子模块虚拟生成桩基础模型，桩基础模型与工程地质模型进行碰撞分析检查，获得相关碰撞信息和属性信息，进而对桩基础模型进行桩基承载力分析、沉降变形分析，获得定量化分析评价结果，同时将产生的定量化分析数据进行存储并进行可视化展示，为岩土勘察设计人员提供定量化的精准数据支撑，有利于提高勘察设计方案的科学性、针对性、合理性。基于轻量化的工程地质模型，导入设计单位已设计完成的桩基础模型、基坑模型，进行相应碰撞检查和定量化分析，通过桩基优化单元模块，进一步复核设计成果的可靠度，形成可优化的建议，反馈有价值的数据，有利于勘察与设计跨阶段协同工作，有利于降低工程潜在风险，提高工程勘察设计成果的可靠度。将岩土工程勘察设计成果和相关分析评价结果进行数字化交付和统一管理，进而对各类成果数字化归档并形成企业数据资产，对工程项目的建设单位、设计单位和施工单位提供各类岩土工程数据成果发布、展示、应用和交付服务，为项目参加各方提供岩土工程数据可视化浏览、分析和查询的平台，进一步提升岩土工程勘察设计企业数字化管理和服务水平；从而实现智慧城市概念的推广与应用。However, the current three-dimensional GIS system has several key technical problems, such as effectively combining BIM with GIS and then visualizing, integrating, quantitatively analyzing, collaboratively applying and digitally managing multi-source heterogeneous data, forming an application system that integrates three-dimensional visualization and integrated display of multi-source data of ground, surface and underground geotechnical engineering, quantitative analysis and evaluation of geotechnical engineering, cross-stage collaborative application of multiple disciplines in survey and design, and digital delivery and management of data results. This is conducive to improving the digital level of technical consultation of survey and design companies in the field of multi-discipline integration of geotechnical engineering, and is conducive to improving the management level of government and industry for urban underground space development, construction and operation and maintenance.
