廖坊水利枢纽库区防护工程河西堤地基变形计算

Calculation on foundation deformation of Hexi dyke as protective engineering of Liaofang reservoir area

为了确保河西堤能够作为廖坊水利枢纽库区的防护工程,对其地基变形进行计算:采用规范法计算地基沉降量,并利用牛顿三点插值求取经验系数;运用太沙基一维固结理论和化引当量层法计算固结曲线.通过分析可知,地基承载力满足要求,地基沉降在规范允许值以内,固结较快.

The calculation of foundation deformation of Hexi dyke which is regarded as protective engineering of Liaofang reservoir area is made.Using standard method calculates foundation settlement amount, and Newton three point interpolation for experience coefficient; calculating consolidation curve by Terzaghi one-dimensional consolidation theory and equivalent layer method.Through analyzing the data,foundation bearing capacity meets requirement,settlement amount less than standard allowable value,and consolidation fast.
