摘要
结合武汉世茂龙湾一期二标段深基坑工程实践,为满足基坑支护方案的安全、经济、方便施工,根据地质条件、场地环境条件对支护方案进行优化选型,采用等值梁法进行悬臂桩加锚杆的支护结构设计,计算结果表明,该支护体系可以较好保证支护结构位移在安全范围内、支护体系安全高效,对周围建筑物影响小,节省工程费用,可为软土地区类似深基坑支护体系的设计、施工提供理论依据。
The anchored soldier pile wall as the deep excavation supporting system was used in the second contract package of the First Phase of Shimao Longwan Project in Wuhan. In order to meet the requirement of safe, cost effectiveness and con- struction simplification, the supporting system was optimized based on the subsurface conditions and the adjacent constrain en- vironment. The anchored soldier pile wall was analyzed with equivalent beam method. The results indicate that the selected supporting system is adequate for the excavation. The system is satisfactorily controlled the lateral deflection, minimize the im- pact on the adjacent building structures and is also cost effective.
