某条形承台的桩基受力探讨

Study on Forces Distribution of Pile Foundation with a Strip-type Platform

为研究某条形承台桩基的内力分配,使桩基受力均匀,文中基于一个简单模型,采用midas Civil有限元程序建模,通过改变承台抗弯刚度、桩基直径和桩基间距等参数,逐级加载,比较不同影响因素对承台桩基内力分配的影响,阐明桩基受力分配特性,并提出使桩基受力均匀的措施。

In order to study the forces distribution of pile foundation with strip-type platform and make the pile foundation stress uniform,based on a simple model,the finite element procedure Midas civil is used to compare the influence of various factors on forces distribution of pile foundation by changing the bending stiffness,pile diameter and pile spacing,clarifying the characteristics of pile foundation stress distribution,and proposing measures to make the pile foundation stress uniform.
