A Simple Method for Estimating the Shear Strength Ratio of Soft Peaty Soils

摘要

A simple method for estimating the shear strength ratio of peaty soils is proposed after confirming the applicability of the critical state concept to peat by performing a series of constant volume ring shear tests on peat. The method does not require the traditional means such as a series of consolidated undrained shear strength tests. Required parameters are the initial in-situ undrained shear strength and the pressure-void ratio relationship of a given peat. Field data have shown the feasibility of the method.
