  Soil liquefaction vulnerability assessment of Sylhet city based on SPT value

  By Abujar Gifari, Mushtaq Ahmed, Shriful Islam, Md Mohaiminul Hassan Sojib

  Abstract: Bangladesh is an earthquake-prone country due to its geographic location. Sylhet, a divisional city, is situated in Zone IV, the most seismically active area in the country, according to the Bangladesh National Building Code (BNBC). A major earthquake can cause devastating effects in the subsurface, such as liquefaction, landslides resulting from a reduction of soil shear resistance. In this study, liquefaction potentiality of soil in Ward No. 9 of Sylhet …

  Assessment of Liquefaction Potential Index for Sylhet City considering Maximum and Average Amplification Factor

  By Md. J. B. Alam, Shriful Islam, Nur M. R. Hoque, Shilpy R. Basak, A. I. Shuvo, S. K. Das

  Abstract: Soil liquefaction often occurs in saturated or partially saturated silty or sandy soil when an earthquake generates dynamic cyclic stress in the soil mass, reducing shear strength and stiffness. This study aims to assess the seismic soil liquefaction hazard potential for Sylhet City using shear wave velocity profiles of 49 boreholes. Factor of Safety (FOS) was evaluated taking into account shear wave velocity and maximum intensity of surface acceleration corresponding …
