Wetting of coarse-grained soil under equal stress ratio path

State Key Lab of Coastal and Offshore Engineering, Dalian University of Technology, Dalian 116024, China

摘要

摘要: 采用古水面板坝玄武岩堆石料进行了等应力比路径下的粗粒土湿化试验。试验结果表明,在等应力比路径下的土体的湿化变形不仅受应力状态的影响还受加载应力路径的影响。在传统湿化变形公式中引入应力路径参量,并采用体积应力和参考应力水平描述应力状态对湿化变形的影响,建立了等应力比路径下的湿化变形公式。所建立的湿化变形公式能够很好地描述等应力比路径下的粗粒土湿化变形。

Abstract: The wetting tests of coarse-grained soil under the equal stress ratio path are performed using the basalt rockfill of Gushui concrete face rockfill dam. The tests results show that the wetting deformation of soil under equal stress ratio path is affected by stress state and loading stress path. The stress path is added in the traditional wetting deformation formula, and the volumetric stress and reference stress level are used to simulate the influences of stress state on the wetting deformation. A formula for the wetting deformation under equal stress ratio path is developed. The developed formula can accurately simulate the wetting deformation of the coarse-grained soil under equal stress ratio path.
