深圳地铁一期工程少年宫站开挖基坑围护结构采用1∶0.3的放坡结合土钉加预应力锚索联合支护体系。根据设计、施工需要,对该站进行了地表沉降、地中水平位移、土钉及锚索应力、水位、基底回弹等项监测。通过对各项监测成果的分析、预测和反馈,为信息化设计和施工提供了可靠的依据。
The excavation of the excavation foundation of the Juvenile Palace Station in Shenzhen Metro Phase I project uses a 1: 0.3 grading combined with soil nailing and prestressed anchor-cable joint support system. According to the design and construction requirements, the station was ground surface subsidence, horizontal displacement in the ground, soil nail and anchor stress, water level, basement rebound and other items monitoring. Through the analysis of the monitoring results, forecast and feedback, for the design and construction of information provided a reliable basis.
