摘要
文昌乐都会购物中心工程由于项目场地等条件的限制采用逆作法施工,根据该工程实际情况列举了该工程逆作法采用的施工顺序和施工方案,通过两个典型的施工工况对支撑内框架和SCW混凝土挡土墙进行承载力、抗倾覆稳定性、抗隆起稳定性和抗渗流稳定性验算,提出工程逆作法在设计阶段的承载力和稳定验算方法,最后阐述了逆作法在设计和施工中的注意事项。
According to the restriction of the project site in Wenchang Tesco shopping center,this project used top-down method.Based on this project,this paper listed the construction sequence of the project and the construction plan.According to two typical construction conditions,this paper calculated the bearing capacity,stability against overturning,stability against basal heave and stability against hydraulic failure of the inner support frame and the SWC concrete retaining wall.Finally we put forward the checking method of the bearing capacity and stability,explained the difficulty of top-down method in design and construction.
