摘　　要：承压水问题已成为影响深基坑工程顺利实施的重要因素。结合某深基坑工程实例,介绍了在周边环境复杂的深基坑工程中,针对不同保护要求采取"降水"与"隔水"相结合的承压水控制方法的设计与应用。工程实践表明:深基坑工程中根据工程特点采用多种承压水处理措施相结合的方法相对于常规方法,既节省基坑工程造价,又能较好地保护周边环境,是合理可行的。Confined groundwater is an important issue which should be carefully considered in the design and construction of deep foundation pits.The measures of controlling confined groundwater were introduced according to different environment protection requirements in a deep excavation in Shanghai.The united method of dewatering and cutoff was adopted in this project.This method had advantages of both cost saving and ensuring the safety of the adjacent environment.It was shown that the method was reasonable and feasible.
