考虑土体流变时土压力计算的条分法

Considering the Slice Method of the Soil Pressure Calculation at the Soil Mass Rheology

当土体具有流变特性时,支挡结构上的土压力将随时间发生变化.在描述土体的两个重要参数中引入时间参数以描述土体的流变特性,并应用条分法计算土体具有流变特性时支挡结构上的土压力.土体的流变特性的两个参数可由实验得出,在此基础上,对于任意形状、堆载及分层的土体.都可以由本方法计算出支挡结构上任意时刻的土压力,从而为支挡结构的设计及施工提供理论依据.

At the soil mass with rheological property, the soil pressure of the supporting structure will change with time. In describing the two important parameters of the soil mass, this paper introduces the time parameter to describe the rheological property of the soil mass, and applies the slice method to calculate the soil pressure of the supporting structure al the soil mass with rheological property. These two parameters describing the rheological property of the soil mass can be obtained by experiments. On this basis, for any shape, heap and stratified soil mass, this method could work out the soil pressure of the supporting structure at any time so as to provide the theoretical basis for the design and construction of supporting structure.
