摘要
在西安某大厦深基坑支护工程中采用钢绞线预应力锚索与SMW工法桩联合的基坑支护方案。通过对围护结构及周边环境的跟踪监测数据进行分析,探讨基坑开挖过程中支护结构的变形趋势及其对周边环境的影响,得出支护结构的内力、坑周深层土体水平位移（测斜）随时间变化的规律,实现了信息化施工。结果证明,该支护形式能保证基坑开挖稳定性,为黄土地区中的基坑支护提供了新的选择。
In a building project of deep foundation excavation supporting in Xi＇ an, the supports scheme of steel strand prestressing anchor cable with SMW pile method was adopted. According to the analysis of retaining structure and surrounding environment monitoring data, this paper discussed the tendency of supporting structure deformation and its influence on the surrounding environment in excavation process, got the rule of the internal force of retaining structure and deep horizontal displacement around foundation excavation below of soil （inclinometer） with time, and the information construction was realized. The results demonstrate that the support form can guarantee the stability of foundation excavation and provide a new choice for the foundation excavation supporting in the loess area.
