摘要
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。
Open-cut slopes of 1：0.3 gradient reinforced by soil nails and pre-stressed anchoring cables are adopted for the foundation pit of Shaoniangong station of phase 1 of Shenzhen Metro. On basis of the requirements of the design and construction of the station, ground surface settlement, horizontal displacement of ground, stress of soil nails and anchoring cables, water table and rebound of foundation floor are monitored. By means of analysis on and prediction and feedback of the monitoring results, reliable reference can be provided for the information-aided design and construction of Metro stations.
