软土的单向压缩的应力应变关系研究

【摘要】 本文根据土体的压缩试验曲线,给出先期固结应力的简化计算方法,避免了图解法确定中目测曲线的最大曲率点的困难,由此确定的前期固结压力一般为其下限值;另外,从土中任意一点任意时刻的一维变形出发,推导土体竖向应变(一维变形情况)与有效应力的关系式。更多还原

【Abstract】 In this paper,on the basis of the comp res-sion test cur ve of the soil,predigestive caculating method of preconsolidtion pressure is giv en.It avoids the difficulty in eyeballing the most curvature point in the diag rammatizing method,the preconsolidtion pressu re for this to be decided is comm only lower limit value;In addit ion,from one-dimen-sion distortion of rando m one point a nd random one time of the soil,we deduce the connection fo rmula between the verti-cal strain and affective stress in th e soil.更多还原
