Geological Characteristics and Instability Mode Analysis of Giant Karst Caves Crossing Bridges
Nstrate the feasibility of the bridge plan,the morphology and geological characteristics of the karst cave were identified through comprehensive survey methods,and the stable state of the karst cave was analyzed.The results show that the karst cave is currently in a stable state,and the quality level of the roof rock mass is Grade Ⅲ.The analysis results provide detailed geological basic data for subsequent stability evaluation and bridge foundation design,which can provide reference for similar projects.
