A dam shoulder karst cave gap layered processing method and device driven by three-dimensional simulation

Abstract

This application provides a three-dimensional simulation-driven method and apparatus for treating karst caves at the dam abutment. The method involves first acquiring multi-source geological survey data of the target karst cave on a server to determine its characteristics, spatial relationships, and original state parameters. A three-dimensional geological structure model including the dam body and foundation is then constructed. Next, a finite element analysis model coupling the dam foundation and dam body is built using experimental data and engineering specifications to simulate and output the baseline values ​​of safety evaluation indicators before treatment. Multiple elevation-boundary layered treatment schemes are designed, and the actual calculated values ​​of each scheme are obtained through simulation under multiple preset working conditions. Finally, through comparison of indicator improvement magnitudes, verification with engineering specifications, and economic analysis, the target treatment scheme that meets safety standards and has the optimal cost is determined. This application improves the scientific nature of karst cave treatment decisions, effectively ensures the stability of the dam foundation structure, and reduces overall construction costs.
