Abstract

In this paper, the potential of the often-saturated sandy soils that occur within the uppermost sub-surface stratigraphy across the Bangladesh plains to experience initial liquefaction due to seismically induced pore water pressure is evaluated. Bore hole logs from development projects were collected. Standard Penetration Test (SPT) values from the drill holes were utilized as the primary data and a widely practiced computational method was employed to estimate the liquefaction potential. The analysis of data indicated that the uppermost portion of the sandy soil layer within 20 m of the surface is loose and sensitive to liquefaction under the influence of ground shaking induced by earthquake having a peak acceleration of 0.15 g. Recommendations to control the liquefaction phenomenon in the light of the country's environment are included.

Liquefaction of the Alluvial Soils of Bangladesh

St. Louis, Missouri

In this paper, the potential of the often-saturated sandy soils that occur within the uppermost sub-surface stratigraphy across the Bangladesh plains to experience initial liquefaction due to seismically induced pore water pressure is evaluated. Bore hole logs from development projects were collected. Standard Penetration Test (SPT) values from the drill holes were utilized as the primary data and a widely practiced computational method was employed to estimate the liquefaction potential. The analysis of data indicated that the uppermost portion of the sandy soil layer within 20 m of the surface is loose and sensitive to liquefaction under the influence of ground shaking induced by earthquake having a peak acceleration of 0.15 g.
