杭州国际博览中心城市客厅项目构件重量大、高度高,吊装难度高,现场采用720t.m大型塔式起重机进行施工。结合该工程720t·m塔式起重机的受力情况及周边环境条件,介绍了720t·m塔式起重机基础的设计情况,分析了塔式起重机基础的受力情况,分别从两种不同工况对塔式起重机支座进行计算分析,对塔式起重机支座下的混凝土墙受压承载力和混凝土墙下底板的抗冲切承载力进行验算。从实际效果来看,720t·m的塔式起重机基础满足了安全施工的要求。
Hangzhou International Expo Center City living room project components weight, height, lifting high difficulty, the scene with a large tower crane 720t.m construction. Combined with the force of 720t · m tower crane and the surrounding environment conditions of this project, the design situation of 720t · m tower crane foundation is introduced, and the stress of tower crane foundation is analyzed. From two different working conditions Tower cradle bearing the calculation and analysis of the tower crane bearing under the bearing capacity of concrete walls and concrete wall under the punching shear bearing capacity checking. From the actual results, the 720t · m tower crane foundation to meet the requirements of safety construction.
