RISEstimation of Active Earth Pressure Against Rigid Retaining Walls Considering Soil Arching Effects and Intermediate Principal Stress
Publisher: ASCE
Abstract: In this study, a novel analytical approach is proposed for the calculation of active earth pressure on rigid retaining walls considering the influence of intermediate principal stress and soil arching effects. According ...
Strong Mining-Induced Earthquakes Produced by the Fracturing of Key Strata during Deep Coal Mining
Publisher: ASCE
Abstract: As coalmines extend more deeply, strong mining-induced earthquakes occur more frequently; these seriously threaten the safety of underground miners and aboveground residents, as well as the productivity and effectiveness ...
Three-Dimensional Spherical DDA Method for Modeling Friction Problems
Publisher: American Society of Civil Engineers
Abstract: Three-dimensional (3D) discontinuous deformation analysis (DDA) is very suitable for simulating large-displacement behavior of rock masses. One fundamental issue commonly encountered in 3D DDA is 3D friction problems. In ...

Two-Dimensional DDA Contact Constitutive Model for Simulating Rock Fragmentation
Publisher: American Society of Civil Engineers
Abstract: Due to the difficulties of fracture mechanics in dealing with multicrack problems, the continuum-based numerical methods always encounter mathematical problems when modeling rock fragmentation, so the alternative ...
Object-Oriented Contact Detection Approach for Three-Dimensional Discontinuous Deformation Analysis Based on Entrance Block Theory
Publisher: American Society of Civil Engineers
Abstract: Compared with two-dimensional (2D) contact cases, three-dimensional (3D) contact problems are more complicated in both contact geometry representation and contact detection. The entrance block theory proposed by Shi lays ...
Three-dimensional Detection Method for Bridge Surface Defects Based on Line-shaped Lasers
Publisher: American Society of Civil Engineers
Abstract: The measurement and description of the three-dimensional (3D) parameters of bridge surface defects are common technical problems in the field of bridge defect detection. These problems are difficult to solve through ...
