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.
