摘要
通过对塔吊基础的受力分析,在满足地基强度和塔吊基础稳定的前提下,将塔吊基础优化为十字哑铃形,以利充分发挥基础底面截面惯性矩的作用,减少基底受拉面积。同时通过适当的分块,便于在工厂预制、吊装运输和现场拼装,大大方便了塔机基础的安装,节约造价,减少环境污染。
By analyzing the stress of the foundation of tower crane, basing on satisfaying the foundation strength and the steady of the foundation of tower crane, the test optimize the foundation of tower crane to cross dumbbell to make full use of the effect of sectional interial torque of the foundation base and reduce the tension area of the basement. At the same time, by appropriate block partition, it will bring convenient to shop precastion, hoisting transportation and spot assembly, supplying great convenient to the fix of the tower crane foundation, saving the construction cost and reducing the environmental pollution.
