一种预测不同温度下非饱和土相对渗透系数的间接方法
An indirect method for predicting permeability coefficients of unsaturated soils at different temperatures
摘要
Abstract
Research interest in the temperature effect on the permeability of unsaturated soils is growing as a result of an increasing number of geomechanical problems involving thermal effects, such as high-level nuclear waste disposal, buried heat-supply pipelines and high-voltage cables.Based on the research of temperature effects on soil-water characteristic curve (SWCC) of unsaturated soils,an indirect method for predicting permeability coefficients of unsaturated soils at different temperatures is presented by using the method of relative permeability coefficients from the SWCCs.The new expressions are made for the entire suction range of SWCC;and hence it has a broader applicability.Based on the experiments of MX-80 bentonite and loess, model prediaions of relative permeability coefficient at different temperatures with suctions are made,which show satisfactory results.关键词
