Strength Parameters

Basing on the new developed direct shear testing instrument, the biodegradation strength properties and strength parameters of municipal solid waste with higher content of organic matter have been studied. The municipal solid waste is divided into three parts: the material that is easy to be biodegraded, reinforced material that is difficult to be biodegraded and the incompressible solid waste material. The proportions of these three parts are 80%, 5% and 15%, respectively. A series of laboratory tests have been performed for different initial void ratios and different vertical pressures applied on the test specimen. Testing results show that the initial void ratio is the main influence factor for the biodegradation strength of the municipal solid waste, the relationship between the biodegradation shear stress and the shear strain is a strain hardening curve, the biodegradation shear stress gradually increases with the shear strain. Besides, the biodegradation shear strength shows a linear relationship to the vertical pressure applied on the test specimen, and it is in accordance with the law of coulomb. According to the testing results, the biodegradation shear strength parameters of municipal solid waste are obtained. The cohesion varies from 11.5 to 24.0kPa, and the internal friction angle varies from 8.3 to 29.0 degree.

Strength Testing

This paper presents results of shear strength testing of intact and recompacted samples of municipal solid waste (MSW). A method for in situ sampling of MSW from landfills using a push-in sampler was developed and used to obtain intact samples of MSW from a large municipal landfill. Shear strength testing of MSW was carried out using a large triaxial compression apparatus as well as a large direct shear apparatus. The results are presented in terms of cohesion intercept (c′) and angle of shearing resistance ([Formula: see text]) and are compared with those available in published literature. Based on these results and their favourable comparison with this literature, it can be concluded that meaningful shear strength parameters for MSW can be obtained using consolidated undrained triaxial tests on large-diameter intact and recompacted samples. A fairly consistent picture of the shear behaviour of MSW obtained from effective stress paths in triaxial tests appears to suggest that shear behaviour of MSW can be explained using the effective stress principle. It is suggested that recompacted samples could be used for obtaining reasonable estimates of c′ and [Formula: see text] for MSW; however, it may be necessary to use intact samples to establish the pre-failure deformation behaviour of MSW.

A model waste mixing with kaolin, sand, and peat was developed. The physical properties of the waste were compared with the real municipal solid waste (MSW). The influence of unit weight on compression factor, shear strength, and saturated hydraulic conductivity was acquired. In addition, the homogeneous of the soil model was detected using the IWHR 450g-ton centrifuge and the newly developed centrifuge-robot.
