Characteristics of Pore Water Pressure of Anisotropic Consolidation Saturated Silt under Wave Loading
摘要
Abstract
Cyclic triaxial-torsional coupling shear tests were performed by hollow cylinder apparatus under anisotropic consolidation to study the development of pore water pressure in the saturated silt under wave loading.It was found that the relationship between pore water pressure ratio and generalized shear strain of saturated silts under anisotropic consolidation well fits the hyperbolic curve,while pore pressure ratio and vibration cycle ratio can be fitted by the use of power function.According to the Mohr-Coulomb law under ultimate state,the method to calculate limit pore water pressure of less viscous silt was proposed; Comparison between the calculation results and the test results showed that there is a linear relationship between pore pressure ratio and consolidation ratio for both of the calculation results and the test values.In addition,the smaller the Kc is,the less difference exists between calculation results and test values.关键词
