| 摘 要： | 首先，根据滑动体力学模型和竖向弹性地基梁模型进行了湖南大厦深基坑支护结构设计；然后，简单介绍了CSC工法并基于现场监测数据对该深基坑支护方案的合理性进行了分析；最后，运用同济曙光岩土及地下工程设计分析软件进行了深基坑动态施工模拟。现场监测和数值分析结果表明：预应力锚索复合支护结构能有效地控制深基坑变形及地表沉降，从而达到确保深基坑自身和周边建筑物、地下管线等安全；数值分析结果与现场监测结果基本一致。 |

| Abstract: | Firstly,the design of retaining and protection structure for foundation pit is introduced based on slipping mechanics model and elastic foundation beam model. Secondly,the feasibility of CSC method and retaining and protection structure is analyzed,according to monitoring data in situ. Finally,the staged construction process of foundation is simulated by using Tongji University GeoFBA FEM software. The results of field measurements and numerical simulation indicate that prestressed anchor cable and pile-retaining-and-protection structure can effectively control the foundation deformation and surface settlement. |
| Keywords: | rock and soil mechanics prestress anchor retaining and protecting method for foundation pit CSC method construction monitoring numerical simulation |
