摘　　要：在灰岩地带进行地基与基础施工,常会遇到溶洞这样的不良地质情况,溶洞地质会对地基与基础施工造成安全质量方面的隐患,并且地下溶洞分布不规则,无法准确判断溶洞分布位置及体积,增加施工难度及成本控制难度。文中以实际工程为背景介绍岩溶区溶洞预处理技术,通过溶洞预处理设计方案、BIM技术优化施工、现场试验确定施工参数、施工过程的控制以及对溶洞预处理效果进行总结归纳,提出溶洞预处理施工的建议,对保证溶洞处理效果具有重要意义。Bad geological conditions such as karst caves are often encountered in foundation and foundation construction in limestone areas.Karst cave geology will cause hidden dangers in terms of safety and quality of foundation and foundation construction.Moreover,the distribution of underground karst caves is irregular,and it is impossible to accurately judge the distribution location and volume of karst caves,which increases the difficulty of construction and cost control.Based on the background of actual projects,this paper introduces karst cave pretreatment technology in karst area.Through the introduction of karst cave pretreatment design scheme,BIM technology optimization construction,field test determination of construction parameters,control of construction process and summary of karst cave pretreatment effect,the proposed construction technology of karst cave pretreatment is put forward,it is of great significance to ensure the effectiveness of cave treatment.
