基于剪切波速与含水率的抗剪强度测量方法

Research of Soil Shear Strength Measure Method Based on Shear Velocity and Water Content

抗剪强度是土的重要特性。根据剪切波速与抗剪强度关系提出了一种基于剪切波速与含水率的抗剪强度可实现野外长期现场测量的方法,并设计了实现该方法必要装置,对实验土样建立了剪切波速-含水率-抗剪强度模型,将模型与实测数据比较,证明该模型可以满足测量需求。

Shear strength is a important feature of soil. Long-time in the wild shear strength measurement meth- od based on shear velocity and water content is put forward, and the device to achieve the method is designed. Mode of the relationship between shear velocity, water content and shear strength is built and is test by experimental data. the test result show the model can fulfill the demand of measurement.
