Thus, the goal of this paper is to provide a feasibility appraisal of three well-known...

..., it was observed that the numerical models presented a fairly good match to encountered operational problems, providing trust to the applied technique, which indicated that the correlations adopted in the study have a proper application to the geological context of pre-salt carbonates. 1 Introduction Wellbore...

A specially designed PMMA apparatus is developed to allow control confining pressure and pore pressure application on oil sand put inside it. The experimental procedure consists of an image collection process of images obtained with camera...

... of application are ‘from-surface-anddownwards’ bench angle decisions in open pits, and for the numerous slope cuttings needed to reach remote hydropower projects, tunnel, bridge and dam sites, often through strongly varying structural geologies. In rock masses where very few joints and no faults or fault zones...

... to slope face. Sectors 2 and 3 have steeper slope angles and are prone to wedges. The work has demonstrated that the application of a 3D model generated with SfM-MVS workflow for rock slope stability analysis is feasible and can find future application in climbing sites. 1 Introduction The climbing...

... Abstract The aim of this paper is to present a practical application of Fuzzy Controllers and Artificial Neural Networks (ANN) models to analyze the stability of rock slopes defined by unfilled discontinuities. Results from direct shear tests on different boundary conditions and types...

... Abstract With economical and convenient features, soil-nailing wall is widely used in foundation pit maintain engineering. Due to the poor holdability of drilling holes in sand layer, the application of soil nails is restricted. Apparent cohesive force plays a key role in application of soil...

Based on numerous iterations with two-dimensional LEM, it was found that applying a constant D produced large deep-seated failure with lower than expected FOS for the given geotechnical conditions. As an alternative solution to this application, a half-sigmoid...

This study presents experimental technique to estimate the gas/methane production with bioconversion of coal...

... of excavations and tunnel surfaces are modeled by fictitious elements. In this work, the node-centric indirect BEM is employed, where linear triangular elements are used to discretize the domain, and nodes are assigned to the corner of each element. In this paper, the application of this approach is extended...

Abstract The main work presents the application and comparison of two constitutive laws described in different elasto-plastic frameworks: a Hardening Soil model, which fits better to the behavior of stiff soils and a Concrete model, which should describe the mechanical behavior of rocks better...

... of the present approach focuses in the influence of the rheological and fragmentation laws in the evolution of the avalanche. The main contribution of the paper is (i) the development of a rheological model coupled with a fragmentation model, and (ii) its application to a real avalanche. We have made a study...
