One of the primary objectives of this work is to better understand the frictional behavior of joints under shear loads, including the creation of damage zones. Discontinuities have an important influence on the deformational behavior of rock systems. The choice of a general criterion to determine the shear strength of rough rock joints is a general problem that has been investigated for many ye...

Recent theoretical investigations suggest that the rate of river incision into bedrock depends nonlinearly on sediment supply, challenging the common assumption that incision rate is simply proportional to stream power. Our measurements from laboratory abrasion mills support the hypothesis that sediment promotes erosion at low supply rates by providing tools for abrasion, but inhibits erosion a...

Abstract: The shear strength and stick-slip behavior of a rough rock joint are analyzed using the 8 complex network approach. We develop a network approach on correlation patterns of void 9 spaces of an evolvable rough fracture (crack type II). Correlation among networks properties 10 with the hydro -mechanical attributes (obtained from experimental tests) of fracture before and 11 after slip i...

Due to the insufficiency of damage model, on the basis of studying deeply deformation and damage mechanism of the rock mass, considering the process and phenomenon of the damage of rock mass, damage part can be divided into two parts: the damage material and micro defects due to the change of damage material, then this paper puts forward a new definition of damage. Besides it proposes an impact...

The paper presents a new microplane constitutive model for the inelastic behavior of jointed rock masses that takes into account the mechanical behavior and geometric characteristics of cracks and joints. The basic idea is that the microplane modeling of rock masses under general triaxial loading, including compression, requires the isotropic rock matrix and the joints to be considered as two d...
