水平循环荷载下饱和砂土中桩-土相互作用机理的试验研究

Experimental Research on Pile-soil Interaction Mechanism under Lateral Cyclic Load in Saturated Sandy Soil

通过设计详细的模型试验方案,对埋入砂土中的模型桩施加水平循环荷载和水平静载两种力,并通过改变加载频率、循环次数以及桩的埋入深度来进行模型试验。收集了大量的实测数据,进行整理和计算后,对模型桩受以上各种因素的影响进行了比较和分析,得到桩-土之间在上述各种因素综合作用下所表现出来的量化规律。

By designing a detailed plan of the model test,to put two kinds of load namely lateral cyclic load and action-less load on the model pile buried in the sand,and then by changing load frequency,cyclic time and the depth of pile buried in the sand to conduct the model test.After arranging and calculating the vast data which is collected from this test,compared and analyzed the influences on the model piles caused by various factors hereinbefore,it gains the quantified rules of pile-soil interaction under the comprehensive effect of kinds of factors mentioned above.
