Abstract: Based on tests in Lab to weathering loose earth of the Jurassic Period in Chongqing reservoir,the author approaches some basic relationship among natural unit weight,strength parameters,seepage coefficient and water content.Variation of both cohesion and friction angle with natural unit weight and water content are discussed in this paper.testing results settle a parameter foundation for the analysis of start up and stability of loose landslides

Key words: Chongqing reservoir, loose earth, seepage coefficient, strength parameter

摘要： 基于对重庆库区比较丰富的松散土体物质，大量的室内敏感性试验成果，比较详细地分析了松散土体的渗 透系数与含水量、饱和度，强度参数c、值的基本关系，探讨了c、与含水量、天然容重之间的变化特性，为 散体滑坡的启动及稳定性分析奠定了参数基础
