摘要

建立桩土体系的力学模型，并求得静刚度的表达式，通过在湿陷性黄土地区的试桩，得到了浸水前后的桩体导纳曲线，在导纳曲线上找到刚度计算的相关参数，算出浸水前后刚度值，并作出比较，得到刚度变化的幅度。

Abstract

the soil-pile model is established,and the expression of pile’s stiffness is acquired.From the experimental pille in collapsible loess,the adimittance curve is gained,and some correlative parameters are picked up to calculate the pile’s stiffness.The pile stiffness value before soaked is compared with that after soaked
