摘要：
武汉某主楼地下室基坑工程，开挖深度大，基坑周边环境条件复杂，对基坑稳定性控制要求非常严格。通过分析其工程地质条件和水文地质条件，经综合经济、技术比较，最终确定该地下室深基坑部分地段采用部分地段悬臂排桩+部分地段竖向注浆花管+锚喷复合支护，经计算支护后基坑各区段的安全系数均大于1.15，能够保障基坑的稳定。
关键词: 深基坑, 稳定性, 控制对策
Abstract:
The deep foundation pit in Wuhan, the surrounding environment condition of which is complex,who’s stability control requirement is very strict. Through the analysis of the conditions of its engineering geology and hydrogeology conditions, the comprehensive economic and technical comparison, finally determine the basement of deep foundation pit of the partial section cantilever piling , part of vertical injection flower tube and shotcreting composite support, the calculation of foundation pit support after the safety factor of each section are greater than 1.15, can guarantee the stability of foundation pit.
Key words: deep foundation pit, stability, control countermeasures
