Deformation and Protection of Existing Tunnels at an Oblique Intersection Angle to an Excavation
(ASCE, 8/1/2020 1)The response of existing tunnels to adjacent excavation at an oblique intersection angle is still unclear. This study investigated the deformation of an existing tunnel when new excavation was conducted obliquely, based ... -
Fracture Modes of Single-Flawed Rock-Like Material Plates Subjected to Dynamic Compression
(ASCE, 9/1/2020 1)Knowledge of fracture process is critical for understanding rock failure mechanisms. In this study, the fracture behavior of single-flawed rock-like material plates made of mortar was investigated using a Split Hopkinson ... -
A Simplified Method for Seismic Design of Cantilever Sheet Pile Walls Under Infinite Uniform Surcharge Load
(ASCE, 9/1/2020 1)Cantilever sheet pile walls are generally designed assuming the rectilinear distribution of net earth pressure. In this paper, a new method is proposed in the framework of the limit equilibrium approach for the analysis ... -
One-Dimensional Compression Behavior of Calcareous Sand and Marine Clay Mixtures
(ASCE, 9/1/2020 1)More and more oceanic projects involve calcareous sand–marine clay mixtures which behave totally different from pure calcareous sand and marine clay. The effect of clay content on the compression behavior of the calcareous ... -
Control and Stabilization of Fugitive Dust: Using Eco-Friendly and Sustainable Materials
(ASCE, 9/1/2020 1)Untreated soil is prone to erosion and dust generation that result in various environmental and health hazards. The addition of additives has been used as a soil treatment method to tackle this problem. Conventional ... -
