Potential of CMC to Increase the Stability of Shale at a Slope AKM Badrul Alama*, Yoshiaki Fujiib, Shaolin Jahan...

..., it is not possible to determine the strike, dip and characteristics of the weak rock layers that are often encountered in construction practice in our country. This, possibly the main reason, makes the analysis of slope slope stability analysis under design inefficient and unreliable. As a result, during the cutting...

... and increase the clay minerals hydrate inhibitor. The wetting behavior has a great influence on the wellbore stability, the drilling fluid systems need to reduce the drilling fluid interfacial tension and enlarge the wetting angle between drilling fluid and rock medium. The crack geometric characteristics...

... to analyze the ground stability rigorously, the numerical study begins with the simulation of goaf-side stress and the ground condition. Four global models with identical conditions except the width of the yield pillar are built and the effect of the pillar width on ground stability has been investigated...

... issues shall be addressed in accordance with Eurocode EC 7 (ӦNORM EN 1997–1): Design concept for determining excavation and support Determination of safety relevant parameters, including definition of expected behavior and criteria for the assessment of the system stability on the basis...

... Abstract Portal sections of road and motorway tunnels are usually the most demanding parts of tunnel construction because they are usually executed under inclined surface and, in most cases, in areas with poor rock quality. Currently, there is a limited number of investigation on the stability...

... characteristics, various tunnel collapses were systematically classified in this paper through the collection and analysis of the tunnel collapses. They can be classified as mountain tunnel collapses, urban tunnel collapses or submerged tunnel collapses; collapses caused by stability of surrounding rock or caused...

..., evolution of slope stability analysis method, source of uncertain data and Monte Carlo algorithm, and proposes the simulation method of layered slope uncertainty. Through the analysis of the joint structure of the flysch, we put forward two kinds of simulation methods: explicit joint and implicit joint...

.... Accordingly, we have developed a three-dimensional information and communication technology (3D-ICT) system that shows various measurement data in real time on a website and determines the overall ground stability using a newly developed evaluation technique. This report outlines the system, the gives...

... optimally designed post-pillars and back filling of the stoped out areas with cemented rock fill (CRF). About 5% of ore is designed to be left in post-pillars. With side confinement offered by the CRF on to these post-pillars, they shall ensure safety and stability of the surface crown during stoping...

... and gas storage, pump house and surge chamber for irrigation purpose etc. Stability of large underground caverns revolves around interaction of surrounding rock mass with the cavern and its support elements. There are two factors, fixed one such as geological setup, in-situ state of stress and variable...

... Abstract We report experimental research on frictional strength and stability properties of shale fractures during slip. Longmaxi shale, Green River shale and Marcellus shale are selected for constant-velocity and velocity-stepping fracture shear experiments. Combing with theoretical analysis...

... Abstract Although a spherical tunnel face has been reported to enhance the stability of tunnels where the tunnel is excavated using Sequential Excavation Method, the effect of the shape of the tunnel face on the deformation behavior, mechanical stability, and ease of construction...

... angle α corresponding to different failure modes is obtained by statistical method. Moreover, the relationship between the three parameters and the slope stability has been attempted based on shear strength reduction method. The results show that: Four failure modes of consequent rock slope...

.... In case of the deep tunnel, MS system was applied in the consideration of a deep long tunnel. This monitoring system is being applied to the rock slope and tunnel site to verify and optimize the reliability and actually to evaluate the geotechnical stability. real time system acoustic emission...

... anchors are all types of rock anchors, and, except the slope stability anchor, are used to reinforce structures. Generally, a dam anchor is large, and plays a very important role as a structural system supporting the safety of the dam. In this paper, we classified these as structure reinforcement anchors...

... Abstract The authors have been recently involved with the restoration of the various historical masonary structures as well as static and dynamic stability assessment of some natural monumental rock structures. Furthermore, dynamic limiting equilibrium methods (D-LEM) as well as numerical...

... Abstract Following the 2011 Great East Japan Earthquake, it has become important to evaluate seismic stabilities of infrastructures in Japan as well as the structures utilizing underground spaces. Oya tuff,which is one of the famous building stone and is classified into pumice volcanic tuff...
