重庆库区典型松散土体的岩土力学参数敏感性试验分析

Sensitivity Analysis of Geotechnical Physical and Mechanics Parameters to the Typical Loose Earth in Chongqing Reservoir

基于对重庆库区侏罗系泥岩典型风化松散土体大量的室内敏感性测试成果 ,比较详细地分析了天然容重、强度参数、渗透系数与含水量之间的基本关系 ,探讨了C、φ随天然容重及含水量之间的变化特性 ,为散体滑坡的启动及稳定性分析奠定了参数基础。

Based on sensitivity tests in Lab to weathering loose earth of the Jurassic Period in Chongqing reservoir, this paper 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 is discussed too. These testing results settle a parameter foundation for the analysis of start-up and stability of loose landslides.
