Abstract: For decades, researchers have searched for an unsaturated soil effective stress that performs analogously to effective stress for saturated soils and provides some simplifications over net stress and suction approaches. A ...

Abstract: Over the past six decades, significant attention has been paid to the elastoplastic behavior of unsaturated soils. In the past two decades alone, elastoplastic theory for unsaturated soils has been established and experimental ...

Abstract: The seasonal variation of unbound material properties is often significant, and water within a pavement structure is a principal cause of pavement deterioration. A small water content increment will result in a significant ...

Abstract: The at-rest lateral earth pressure coefficient, which is called the k0 coefficient, is an important parameter in geotechnical engineering. An accurate evaluation of k0 is of great significance in both theoretic analyses ...

Abstract: Constitutive surfaces are indispensable for investigation of the behavior of soils. Saturated and unsaturated soils coexist in most engineering problems and it is meaningful to develop constitutive surfaces covering both ...

Abstract: Attention is increasingly paid to the elastoplastic behavior of unsaturated soils. In the development of an elastoplastic framework for unsaturated soils, it is necessary to determine the initial shape of the yield curve ...
