【摘要】 剪切波速是评价场地土动力特性的重要指标。利用软粘土非线性弹性模型、摩尔-库仑强度理论以及土的波动理论,建立剪切波速度与软粘土的抗剪强度的关系式。通过与工程实例比较,本文公式能有效地估算地基的抗剪强度,满足工程实际应用的要求。更多还原

【Abstract】 Shear wave velocity is an important parameter in evaluation of dynamic properties of soil.By using the nonlinear constitutive relationship of soil,More-Coulomb strength theory and soil dynamicstheory,the relationship formula between shear strength of soft clay and shear wave velocity is derived.Through compared the derived calculating method with the field measured of shear strength,it is showthat the method by author derived is effective to calculate soil’s shear strength in term of shear velocity.更多还原
