摘要
讨论抗拔桩设计和计算中的几个常见问题,并结合工程实例对设置抗拔桩对地下结构受力产生的影响进行分析,提出了抗拔桩和压顶梁弹簧系数的计算方法。针对上部荷载和抗拔桩同时作用的地下结构,通过三维有限元分析,给出了其计算结果并提出了可行的设计方案,对地下结构尤其是地铁结构设计具有一些借鉴意义。
The paper discusses several foundational problems about tension pile itself. According to an engineering example,analysis the inflection to underground structures those had set tension piles,put forward the calculation method of the spring factor to tension piles and top pressure beam. At the same time,to those underground structures which have super structures over them,the paper provides calculation results and feasible design scheme through three dimensional finite element analysis. It will have some reference significance for structure design of underground structures,especially subway station.
