Numerical simulation study on the impact of mining excavation on surrounding structures
Excavation of mining foundation pit is an important part of mining engineering,but its process will have a significant impact on surrounding structures.With the increase of mining depth and scale,the problems of ground settlement and horizontal displacement caused by excavation of foundation pits are becoming increasingly prominent,posing potential threats to adjacent buildings,underground pipelines,etc.This article analyzes the stress field changes,ground settlement,and impact on underground pipelines and building foundations during excavation of foundation pits through numerical simulation research.On this basis,measures such as strengthening support and monitoring,implementing isolation and buffering,and reinforcing sensitive structures were proposed to ensure the safety of mining foundation pit excavation and reduce adverse effects on surrounding structures.This is of great significance for guiding the practice of mining foundation pit excavation engineering.
