一种改进的水泥土支护结构抗倾覆验算方法

A Modified Calculation Method of Stability Coefficient of Resisting Capsizing to Cement Soil Supporting Structure

对传统的水泥土支护结构抗倾覆稳定系数的计算方法进行了分析 ,指出其存在的缺陷 ,并从结构设计角度出发 ,按照极限状态的原理推导出一种改进的水泥土支护结构抗倾覆稳定系数的计算方法。克服了传统方法抗倾覆稳定安全系数会随着结构入土深度的增大反而减小的缺陷 。

In this paper, the conventional calculation method of stability coefficient of resisting capsizing to cement soil supporting structure is analyzed and some defects are indicated. From the point of structure design, a new reasonable calculation method of stability coefficient of resisting capsizing is put forward based on the principle of terminal state. It solves the problem that traditional safty factor will deminish along with the augment of the structural depth in the dust, thus it can reflect the mechanism of resisting capsizing to cement soil supporting structure well.
