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。
Combined with the practice of Deep Foundation Pit of Shihlongwan Phase I Project in Wuhan, in order to meet the requirements of safety, economic and convenient construction of foundation pit support scheme, the optimal selection of support plan is carried out according to geological conditions and site environmental conditions, The results show that the support system can better ensure the displacement of the support structure within the safe range, the support system is safe and efficient, the impact on the surrounding buildings is small, and the project cost is saved , Which can provide a theoretical basis for the design and construction of similar deep foundation pit supporting system in soft soil area.
