| 摘 要： | 围垦滩地饱和粉土地基属于软土地基的一种,其含水量高,渗透性差,强夯加固作用使地基土中的孔隙水压力瞬时升高,且短时间内得不到消散,容易出现“橡皮土”。通过现场试验研究了饱和粉土地基在强夯作用下孔隙水压力的响应规律,确定了两遍强夯之间的间歇时间和强夯的影响深度,以便优化强夯参数,正确指导强夯施工。

| Abstract: | The saturated silt foundation of reclamation land is a kind of soft soil foundation,and has high water content and poor permeability,so the pore water pressure in the foundation soil will increase drastically and will not clear off in a short time under a dynamic compaction forcing,and the foundation soil sometimes becomes a rubber soil.In this paper,the response of pore water pressure in the saturated silt foundation to dynamic compaction forcing is studied by making in-situ experiments,and the intermission time between two dynamic compaction forcings and the influence depth of dynamic compaction forcing are determined so as to optimize the dynamic compaction parameters and to correctly guide the dynamic compaction operations. |
