Several mechanisms may coexist to explain initiation and progressive failure due to temperature variation: thermal...

... methods widely used in China, Soil nail wall is reliable, economical and easy to construct (Wei & Cheng. 2010). However, the collapse of drilling holes occurs sometimes when it comes to sand layer, which may fail the construction of soil nail wall. The mechanism of collapse is still not very clear...

... Abstract Stability of weak rock slopes are threatened by structurally controlled mechanisms or mass failure. Shallow depth lignite beds are commonly exploited by surface mining. Preliminary slope stability analysis is carried out by practical tools that perform quick stability investigation...

... Abstract The scenario of deepwater exploration under large thick salt formation is challenger and motivates the development of new technologies to deal with costs, safety and environmental issues. This paper deals with the mechanical characteristic of strong creep behavior of salt rocks...

... are absent. In this paper we will describe a methodology that was developed to prescribe strength as a function of depth by considering the variation of disturbance with depth. Four simple cases were analyzed in Rocscience's Slide to present the impact of disturbance on the failure mechanism geometries...

... of the preexisting defects at different scale (micro-cracks, cracks and joints) and their evolution. To consider the influence of defects on mechanical behavior of the material, the original concept of damage was introduced by Kachanov (1958) for a tensile bar in one-dimension. The scalar damage variable...

... Abstract In the future, most of the deep roadway tunneling will face the high geo-stress environment. Different geo-stress values can make a great influence on the process of deep rock fragmentation by blasting. In this paper, the action mechanism of the geo-stress in the process of rock...

The primary focus here is to adapt the phenomenological result of the role for friction mobilization in small...

... of the surrounding rock material and break it. The rock breakage and its detachment occur because of two distinct mechanisms. Right after the detonation, a compressional stress wave hits the blasthole wall and expands radially within the rock mass, creating radial cracks around the blasthole. Once the wave arrived...

To address this issue, we propose a novel approach to define the direction of the plastic-flow vector using...

... Abstract Tension-shear stress state is complex, which is most likely to induce rock fracture. The macroscopic fracture process of rock is initiation, growth, coalescence of micro cracks until generation of macro cracks. The purpose of this article is to understand the failure mechanism of rock...
