| 摘 要： | 基于相似理论 ,提出了一种新的夯扩桩全模试验研究方法及试验装置。以大直径全套管夯扩桩技术为背景 ,以夯扩变形机理、桩端承载力特性为研究对象进行了室内全模试验 ,分析了该技术条件下的夯扩影响半径。在影响半径之内 ,土体被加密 ,承载力得到提高。通过静力载荷的模拟试验 ,得到了夯扩底提高桩端承载力的大致幅度。

| Abstract: | Based on similar theory,a new method of full pile model test and a new type of experimental equipment are proposed.The tests of rammed pedestal filling pile of large diameter and full-sleeve are carried out in laboratory,and thus laying the foundation of the study on end bearing capacity of rammed pedestal piles.The empirical ramming effect radius is studied.Within the effect radius,soil is squeezed,and bearing capacity of soil is improved.Through contrast static loading model tests,it is found that the end bearing capacity of rammed pedestal pile is much higher than that of non-rammed pile. |
