摘要
采用适用于上海饱和软土的非线性粘弹塑性模型 ,研制了三维有限元软件 .应用该软件对软土地基上填土桥坡的工后沉降进行了三维有限元研究 ,并将计算值与实测结果作了比较 ,认为软土路基的蠕变效应是造成桥坡工后沉降的主要因素 .
The elastic-visco-plastic constitution has been employed for the programming of 3D-FEM for the soft saturated clay in Shanghai. The program has also been applied to the prediction of the post-construction subsidence of fill bridge-slope on the soft clay basement. The comparison between the predicted value and measured value proved that the creep effect is a dominant factor for the production of post-construction subsidence of the fill bridge-slope.
