  Effect of Water Table Position on the Stability of Tunnel

  By Md. Mahmud Sazzad, Shantonu Hore Joti, Md. Mahfuzur Rahman

  Abstract: Tunnel is an underground structure used to convey the traffic. Construction of a tunnel in rock is a difficult task. In instances where tunnels are situated at shallow depths, the stability of the tunnel and its lining is notably affected by the adjacent surcharge loadings resulting from new building constructions or excessive loads on the ground surface. Stability of the tunnel crest also depends on the position of the water …

  DEM Simulation of Macro and Micro-Scale Behavior of Granular Materials during Loading and Unloading

  By Md. Mahmud Sazzad

  Abstract: The present paper aims at comparing the simulated stress-strain behavior of granular materials quantitatively with the experiment and exploring the evolution of the micro-scale behaviors during loading and unloading using the discrete element method (DEM). A numerical sample consisting of 9826 randomly generated spheres similar to the experiment was prepared. The numerically prepared isotropic sample was subjected to loading and unloading under strain controlled condition. It is noticed that the …
