Dynamic Characterization of Sand of Indo-Bangla Border for Seismic Design

Agartala, the capital city of northeastern state Tripura, is growing fast in terms of infrastructural facilities and population due to its global importance by acting as a business corridor for southeast Asian countries through Bangladesh. This region was categorized as Indo-Bangla sedimentary basin which is also identified as a seismically active zone since the number of active faults. Likewise, Chittagong fault has passed near to this region. The present study is an attempt to perform dynamic characterization by performing dynamic laboratory tests on the Holocene age sandy soil collected from different depth as well as varying locations of Agartala. Bender element (BE) tests are carried out on the remolded soil samples. Hence, the present study will offer different dynamic characteristics of sand, which will be helpful to carry out local site effect studies and especially for prediction of severity of liquefaction of this area.
