含水率对滑带土强度参数的影响
The influence of water content on the strength parameter of soil in slip zone
摘要
Abstract
The soil in slip zone is the vital section of the landslide, the strength characteristic has important effect on the stability of slope. Because Huangtupo landslide in Three Gorges Reservoir area has been affected by varia-tion of reservoir water level and rainfall, water content of soil in slip zone is always in the process of changing, this produces much influence on the strength parameter of soil in slip zone. According to this thought, some soil sam-ples in slip zone of Huangtupo’s second landslide near river were taken, undrained quick direct shear test for the soil in slip zone with different water content was conducted. The parameters of internal friction angle(φ) and cohe-sion(C) influenced by water content of soil in slip zone were acquired through test.关键词
