tailieunhanh - Parametric analysis of slope stability for river embankment

This paper has aimed to investigate the slope stability for various conditions like embankment geometry, water level and soil property. The analysis has been performed by using the XSTABL program for di erent slope heights, slope angles and ood conditions with a xed soil cohesion value. Since the rapid drawdown is the worst case for a particular embankment therefore, the analysis has been further performed with di erent cohesion values. From this investigation it has been noticed that the increase of cohesion of soil can increase the stability to a great extent. | VOLUME 4 ISSUE 3 2020 September Parametric Analysis of Slope Stability for River Embankment 1 2 Dhrubo HAQUE Md Isteak REZA 1 Sub-Divisional Engineer Power Grid Company of Bangladesh Limited Dhaka Bangladesh 2 Bangladesh Army Bangladesh Corresponding Author Md Isteak REZA Email isteakbuet@ Received 19-May-2020 accepted 2-Aug-2020 published 30-Sep-2020 DOI http Abstract.
