摘要
根据上海地区软粘土的流变特性提出了一种线性粘弹 粘塑性流变模型 ,运用该模型及自编的有限元程序对上海永银大厦深基坑工程实际挖土、支撑时间及工况进行了严格模拟 ,将开挖过程分成 1 4个开挖步的平面应变二维流变的计算。同时对围护结构水平变位。
A viscoelastic\|viscoplastic constitutive model for soft clay is established based on the rheologic characteristics of the soft clay in Shanghai area.A FEM program which can be used for rheologic research is developed.As an example,Yongyin Tower deep excavation project is caculated for two dimensional rheology simulating practical work situation.The horizontal deflection of retaining wall,the earth's settlement behind the wall,and the distribution of earth's plastic zone are calculated and discussed.
