摘　　要：以广州某溶洞区桥梁工程桩基施工冲桩阶段出现地面塌陷开裂引起周边房屋不均匀沉降为例,通过对塌孔原因分析及对周边房屋影响的评估,提出相应的应急处置预案,并创造性地将自动化监测与人工监测相结合来保证应急处置措施的顺利进行,达到了很好应急处置效果。This article takes the example of uneven settlement of surrounding houses caused by ground collapse and cracking during the pile foundation construction of a bridge project in a karst cave area in Guangzhou.Through the analysis of the causes of the collapse and the evaluation of its impact on surrounding houses,corresponding emergency response plans are proposed,and the combination of automated monitoring and manual monitoring is creatively combined to ensure the smooth implementation of emergency response measures,achieving good emergency response effects.
