摘　　要：文中以某酒店建设项目为例,分析了项目的水文地质条件,从基坑稳定性、基坑土方开挖支护、基坑收底三方面总结了土方开挖要点,总结了地下水控制和地下室抗浮措施。监测结果表明,本工程基坑施工中,深层土体水平位移测点的累计量为18.26~26.32 mm,未超出标准值50 mm;地表沉降变化速率平均值为1.92 mm/d,未超出标准值为3 mm/d,满足设计规范要求。Taking a hotel construction project as an example,this paper analyzes the hydrogeological conditions of the project,summarizes the main points of excavation from three aspects of foundation pit stability,excavation support,excavation bottom,groundwater control and basement anti-floating measures.The monitoring results show that:during the foundation pit construction of the project,the cumulative amount of the deep soil horizontal displacement measurement point is 18.26~26.32 mm,which does not exceed the standard value of 50 mm;The average change rate of land surface settlement is 1.92 mm/d,which does not exceed the standard value of 3 mm/d,and can meet the requirements of the design specification.
