Beside geometry parameter of slope, the flowing of slurry also relate with rheometer property by itself. In this work, the parameter value of sand slurry and clay slurry are measured by SR5 rheometer and set up the relationship between the parameter of sand slurry and clay slurry and plastic parameter of soil sample. In order to provide proper material parameters and intensity parameters to the stability simulation of soil slope in the future. The purpose of this study is discussing the shear stress and strain rate relation under different silt allocated proportion and different water content, and the viscosity coefficient and yield shear stress are estimated. The experimental results show that when the content of water increases, the intensity of soil and degree of viscosity will reduce. With the same content of water, while the percentage of clay increases, yield shear stress and viscosity will increase. Shear strain rate also will increase when shear stress become bigger in the different silt allocated proportion which conforms to Bingham model. In mechanics aspect, beside the viewpoint of consideration static balance, still have to match the Bingham parameter (yield stress, τB) and the combination of Mole-Coulomb force. The PLAXIS v7.2 is used to establish model to simulate various conditions of stress distribution, size and displacement for sandy soil slope. Hoping we can understand the relationship between the slip of soil slope and parameters of strength by discussing the plastic behavior of sandy soil. 丁原智 2007 學位論文 ; thesis 101 zh-TW |
