摘要 岩溶地区地质情况复杂,溶洞的大小和连通性存在不确定性,某桥梁桩基施工过程中存在着塌孔、路面塌陷等突发情况,通过采用多种手段进行施工期间补充勘察,探明溶洞的大小及连通性,提出多个调整桥梁基础设计方案进行分析比选,结合工程安全性、进度、造价等综合因素推荐合理方案,并顺利实施。 s:The geological situation in karst areas is complex,and there are uncertainties in the size and connectivity of karst caves.During the construction of a bridge pile foundation,there are sudden situations such as hole collapse and road surface collapse.During the construction period,various means are used to conduct supplementary surveys to explore the size and connectivity of karst caves,propose multiple adjustment bridge foundation design schemes for analysis and comparison,and recommend reasonable schemes based on comprehensive factors such as project safety,progress,and cost,which have been successfully implemented.
