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。
The problem of confined water has become an important factor affecting the smooth implementation of the deep foundation pit project. Combined with a deep excavation project example, the design and application of a confined water control method combining “precipitation” and “water separation” for different protection requirements in a complex deep foundation pit project with surrounding environment is introduced. . The engineering practice shows that the combination of multiple pressure-bearing water treatment measures based on the characteristics of the project in the deep foundation pit project is reasonable and feasible compared with the conventional method, which not only saves the cost of the foundation pit project, but also can better protect the surrounding environment.
