摘要
建立了混凝土预制拼装多用塔机基础的有限元模型,分析了正常使用状态下的各元件受力情况以及塔基基础与地基的相互作用。预制拼装塔机基础可以满足正常使用要求,地基的弹性模量对压应力分布有明显影响。
Finite element model of prefabricated concrete tower crane base is set up in this paper,analysis on different parts of the base and the interaction between the base and its subgrade is down. The result shows that the crane base is satisfied for common conditions, the stress distribution between the base and its subgrade is influenced by the elasticity of the subgrade.
