摘　　要：为了保证岩溶地区建筑物在建设和使用时的安全性,以某住宅建筑物为研究对象,利用地质雷达和钻探法查明其所在区域的岩溶发育体的位置、形态等,并将地基划分为三个区域:较稳定区、较不稳定区、不稳定区。针对不稳定区,拟采用注浆法处理,阐述了注浆方案和工艺,并用全站仪对处理后的岩溶地基沉降进行监测,监测成果表明地基沉降可控制在10 mm以内,可为类似项目勘察设计提供理论指导。In order to ensure the safety of buildings in karst areas during construction and use,a residential building was taken as the research object.Ground penetrating radar and drilling methods were used to determine the location and shape of the karst development body in the area,and the foundation was divided into three areas:relatively stable area,relatively unstable area,and unstable area.For unstable areas,the grouting method is proposed to be used for treatment.The grouting scheme and process are elaborated,and the settlement of the treated karst foundation is monitored using a total station.The monitoring results show that the foundation settlement can be controlled within 10mm,which can provide theoretical guidance for similar project survey and design.
