Abstract

This paper discusses the influence of deep foundation pit support on the stability of underground structures and design optimization from the perspectives of problem causes and optimization paths. It proposes methods such as strength parameter calculation based on detailed geological surveys, multi-dimensional waterproofing system design, selection of appropriate support forms, and coordinated excavation planning. Corresponding research on the influence mechanisms of support and optimization strategies is conducted. The results aim to demonstrate that these optimization paths can effectively solve problems such as displacement caused by insufficient support strength and seepage failure due to waterproofing failure, thereby ensuring the stability and durability of underground structures.
