岩溶地区基坑工程及桩基础施工对地铁结构影响的风险分析

Risk Analysis of Influence of Foundation Pit Engineering and Pile Foundation Construction on Subway Structure in Karst Area

岩溶地区的地铁结构容易受外部环境变化的影响,邻近工程进行连续墙、桩基础、支撑立柱、溶洞处理、基坑开挖、基坑降水等分部分项工程施工时,均可会对地铁结构造成较大威胁。本文通过对拟建的广州设计之都基础设施综合开发项目进行风险评估与分析,为后续地铁保护项目管控提供一定参考,提升地铁保护工作的力度。

The metro structure in karst area is easily affected by external environmental changes,the constructions of continuous wall,pile foundation,supporting column,dissolved cavern treatment,foundation pit excavation,foundation pit precipitation and other sub-projects in adjacent projects can pose a great threat to the metro structure.Through the risk assessment and analysis of the proposed Guangzhou Design Capital infrastructure comprehensive development project,this paper provides certain reference for the subsequent control of metro protection projects and improves the level of metro protection work.
