Abstract

The seismic hazard is relatively higher in Northern India due to the presence of the Himalayas encompassing many regional features like Main Boundary Thrust (MBT), Main Central Thrust (MCT) and Himalayan Frontal Thrust (HFT). Implicitly, estimation of liquefaction potential becomes of paramount interest due to the presence of deep soils in this region. Indo-Gangetic basin is composed of thick alluvium deposits where thickness of sand layer may extend up to 30 to 40 m. In the present study, a fully coupled finite element analysis is incorporated for modeling liquefaction phenomena for soil domain up to 30 m depth subjected to cyclic ground excitation of 0.2 g ground acceleration. Moreover, a parametric study is carried out to explore the liquefaction behavior on saturated sand layer of variable thickness. The ratio (Hliq/Hsand) is increasing with depth (0.5, 0.8, 0.833) highlighting the effect of drainage path.
