下穿通道深基坑支护工程的设计与施工

该文分析了武汉友谊大道下穿通道基坑支护工程的重点和难点,介绍了该工程基坑支护的设计、施工与监测情况。通过优化设计,基坑支护结构采取SMW工法连续墙加内支撑的支护体系,地下水控制采用SMW工法形成侧向止水帷幕和中深井降水相结合的处理措施,并运用了信息化施工管理技术。

Design and Construction of Deep Foundation Pit Supporting Engineering of Underpass Tunnel

The focal points and difficult points of the deep foundation pit supporting engineering of the underpass tunnel in Friendship Road of Wuhan are analyzed in this paper, and the design, construction and monitoring condition of the engineering foundation supporting are introduced. Through optimizing design, the supporting structure in the foundation pit uses the SMW technology of continuous wall plus inner-supporting system. The groundwater is controlled by the treatment measures of the lateral water-proof wall of the SMW technology combined with the mid-deep-well dewatering. In the construction process, the information construction management technique is applied.
