Research on the 3D Visualization Method of Web-Based Seismic Wave CT Results and the Application in Underground Caverns

Abstract

This paper introduces a novel 3D visualization technique for seismic tomography results utilizing WebGL technology, which operates independently of specific software platforms and offers highly efficient visualization. The method constructs the mesh using wave velocity as a reference point, applies vertex and surface coloring techniques to the model, and integrates CT detection data, resulting in a detailed color rendering and a clear visual representation of the model. The visualization outcomes are presented on an intelligent construction platform with a response time maintained within 2 s. To validate the efficacy of the proposed method, it was applied to the underground cavern project of a hydropower station and compared with the geological 3D design software developed independently by the Northwest China Institute of Architectural Engineering. The comparative results demonstrate that the proposed visualization technique effectively identifies weak geological layers and displays the distribution of surrounding rock types in underground structures. This provides intuitive references for devising support schemes for underground structures and facilitates digital management during project construction.
