Simple estimation method of in-situ strength of sedimentary solid waste ground

Abstract

In-situ direct shear and earth pressure tests were developed for estimating strength of solid waste materials (SWM). Strength properties of solid waste materials were investigated in different sites. Strength parameters of cohesion of frictional angle are obtained from the in-situ direct shear and earth pressure tests. The in-situ earth pressure test was conducted by putting several bars in a line. Strength parameters are evaluated from test results of the in-situ earth pressure test in different embedded length of pile. Cohesion and frictional angle obtained from the in-situ direct shear and earth pressure tests are correlated respectively. The in-situ earth pressure test is very simple method. It is therefore that the strength property of solid waste materials can be estimated as an approximate value.
