Integrated method for building 3D regional geological model in mountainous cities

Abstract

The invention discloses a three-dimensional geological model constructing and integrating method for a mountain city area, and belongs to the field of three-dimensional geological models. The construction of the three-dimensional geological model for the mountain city area is achieved through the method; due to the fact that the features of the geological structure of the mountain city area are combined, according to the process of constructing a sectional framework, drawing a section and constructing a geological model and the method for constructing the geological model by utilizing the section, the construction of the three-dimensional geological model for the mountain city area is completed more accurately. According to the three-dimensional geological model constructing and integrating method, visualization integration of the three-dimensional regional geological model is further achieved, and a data basis is provided for application analysis of geological topics. Moreover, with regard to the result data of the formed three-dimensional regional geological model, visual integration simulation on a three-dimensional digital city platform is achieved, and real-time geological analysis of the three-dimensional geological model can be achieved in a three-dimensional scene.

Description

technical field [0001] The invention belongs to the field of three-dimensional geological models, and in particular relates to an integrated method for building a three-dimensional geological model of mountainous urban areas. Background technique [0002] Based on various original data, 3D geological modeling establishes a digital model that can reflect the shape of geological structures, structural relationships, and changes in the internal attributes of geological bodies. These raw data include boreholes, profiles, seismic data, isobath maps, geological maps, topographic maps, geophysical data, geochemical data, engineering survey data, hydrological monitoring data, etc. Through appropriate visualization methods, the digital model can display the virtual real geological environment, help users intuitively understand the geological environment, and facilitate the exchange of ideas between users at different levels. More importantly, model-based numerical simulation and spa...

Problems solved by technology

At present, a series of explorations have been made on the construction of regional geological models in some large cities on the plains. However, in view of the relatively simple geological structures in plain areas, and relatively few geological structures such as faults and folds, it is not enough to construct regional geological 3D models in mountainous cities. It has too much reference value, so it is still a problem that we urgently need to solve for the construction of the 3D geological model of mountainous urban areas

[0010] Existing technologies cannot effectively integrate and apply 3D geological model data in a 3D visualization platform environment
