摘要
简化的Mesri蠕变模型参数简单 ,所需的三个参数可通过常规的三轴流变试验获得。本文采用该模型描述桩底土的蠕变行为 ,用桩的Mindlin附加应力公式计算桩基桩端平面下的附加应力 ,建立了一套计算桩基工后沉降的简单实用的方法 ,同时对相应桩基的工后沉降进行了现场长期监测。
The parameters of simplified Mersi Creep Model are quite simple and its three parameters can be obtained by normal tri axial rheology test. In this paper, this model is used for describing the creep of soil under the pile. The Mendlin formula of additional stress for pile is used to calculate the additional stress under the surface of the pile end. A simple and practical method is set up for calculation of settlement of the pile base after its construction. A long term site monitoring was carried out on the settlement of pile base after construction. A comparison of calculation results with those of monitoring shows that the former can be used for primary design.
