| 摘 要： | 针对散体材料桩复合地基承载力随时间延续而增长的现象，基于复合地基承载力计算的面积比公式，分别对桩体和桩周土体承载力的时效进行分析，提出了一种考虑时效的散体材料桩复合地基承载力的方法，并给出了公式中重要参数的参考值。最后结合某一工程实例，对一具体的碎石桩复合地基的承载力进行时效分析，其结果表明，在进行散体材料桩复合地基的承载力计算时考虑时效是很有必要的。

| Abstract: | The phenomenon that the bearing capacity of the discrete material pile composite foundation is increased by time-varing is fully discussed in this paper.The timeliness of both discrete material pile and the surrounding soil is discussed respectively.Then,on the base of the Area-ratio Formula,the bearing capacity of this composite foundation with consolidation of aging effect is proposed.Moreover,the reference value of parameter is also offered.Finally,a case history of rushed stone pile composite foundation is employed to study the timeliness of the foundation's bearing capacity.The result shows that it's quite necessary to consider the aging effect when calculate the bearing capacity of the composite foundation. |
