摘要
文章研究了循环荷载作用下软土地基的循环累积变形特性,将其等效为静力蠕变过程,采用拟静力的方法,建立了弹塑性的循环蠕变模型并提出了计算方法。以桶形基础为例,对循环荷载作用下软粘土地基的累积变形进行了计算、分析。
The characteristics of cyclically accumulated deformation of soft soils under the action of cyclic loads are studied,which are equalized as a process of static creep.A pseudo-static elasto-plastic cyclic creep model is established and a calculation method is proposed.Taking a bucket foundation as an example,the cyclically accumulated deformation of soft soils under the action of cyclic loads in calculated and analyzed.
