摘　　要：文中以某18 m深基坑工程为例,分析场地的工程地质与水文地质条件,研究基坑工程的稳定性,制定支护方案、地下水控制措施,并监测基坑变形量。结果表明,基坑侧边各土层自立高度为0.70~4.44 m,突涌稳定性安全系数为0.21~0.37,支护桩顶部沉降累计值9~13 mm,水平位移累计值18~25 mm,满足设计要求,该研究成果可为类似基坑工程建设提供参考。Taking a 18m deep foundation pit project as an example,this article analyzes the engineering geological and hydrogeological conditions of the site,studies the stability of the foundation pit project,formulates support schemes,groundwater control measures,and monitors the deformation of the foundation pit.The results show that the self-supporting height of each soil layer on the side of the foundation pit is 0.70~4.44 m,the safety factor of sudden surge stability is 0.21~0.37,the cumulative settlement of the support pile top is 9~13 mm,and the cumulative horizontal displacement is 18~25 mm,which meets the design requirements and can provide reference for similar foundation pit engineering construction.
