The structure is comprises of 12 m long concrete sheet pile combined with concrete pile having a diameter of 60 cm and length of 36 m. During the early filling for the road widening, however, landslide occurred and the structure collapsed. An alternative solution was therefore required. Soil profile at the site consists of very soft to soft clay having a thickness of 25 – 28 m. This layer is under laid by medium clay and dense sand up to 35m below the ground surface. Finite Element analysis was performed by modeling soil as the Mohr-Coulomb elastic-plastic material and by modeling concrete sheet pile and pile as elastic-plastic beam elements. Calculation results showed that safety factor for existing condition before filling was 1.1. Filling for the road widening reduced safety factor to less than 1.0 and resulted in instability of river slope and failure of the structure. It was decided that the combination of concrete sheet pile and slab-on-pile structure was the optimum solution. With this solution, safety factor of the river slope was then increased to more than 1.25 as the minimum requirement. © 2009 IOS Press.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Dense sands,Elastic-plastic beam,Existing conditions,Ground surfaces,Indonesia,Mohr-Coulomb elastic-plastic material,Optimum solution,Reduced safety factor,Riverbank protection,Road widening,Sheet piles,Slab-on-pile,Soft clays,Soil profiles,Spun pile[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Concrete sheet pile,Concrete spun pile,Finite element method,Landslide,Riverbank protection,Slab-on-pile[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.3233/978-1-60750-031-5-2629[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
