Stability Analysis of Landfill Liner System Based on Numerical Simulation

Abstract:

Although ABAQUS is one of the most powerful non-linearly finite element software, it is lack of interface Duncan-Chang constitutive model, which is one of the generally used soil numerical method in China and worldwide. Subsequently, ABAQUS can not widely used in soil numerical method. To improve this situation, a new interface Duncan-Chang constitutive model was developed based on the preliminary direct shear test results through secondary development. Combined with practical engineering, the efficient model was established. Compared with smooth geomembrane/geotextile interface, the shear stress of reinforced geomembrane/geotextile interface increases obviously, and the sliding displacement decreases obviously. It supports our assumption that the reinforced geomembrane can improve interface shear strength and stability of liner system.
