Abstract

The Singkil Sub-district of Aceh Singkil District comprises alluvium deposits with a relatively low ultimate bearing capacity. The ultimate bearing capacity of the soil is closely related to the safety of a building. The important thing related to estimating the ultimate bearing capacity of the soil is in-situ soil investigation. This study aims to estimate the spatial distribution of soil ultimate bearing capacity using field test data in the Singkil Sub-district. Estimating ultimate bearing capacity is useful to provide an initial picture for various planning and infrastructure development activities in the study area. Twenty CPT in-situ tests have been obtained from various field works in Aceh Singkil Regency. Field data analysis, based on empirical methods, was carried out to obtain the value of the ultimate bearing capacity of the soil at the test location. Then, the estimated distribution of the maximum bearing capacity obtained was carried out. The zoning map of the distribution of soil ultimate bearing capacity in the study was developed from this research. This map can be used as a form or effort of disaster mitigation by various stakeholders involved in planning and building various infrastructure facilities in the Singkil Sub-district

Abstract

Landslides frequently occur on the Subulussalam – Lipat Kajang road segment as a result of heavy rain that lasts for a long time. In addition to landslides, the Subulussalam area is vulnerable to earthquakes because it was once the site of a tectonic earthquake with a magnitude of 6.7 on the Richter scale. The extent of the destruction, as well as the number of victims, was caused by a lack of emergency planning. This research aims to see if the slope conditions are safe when subjected to an earthquake load and if appropriate handling methods can be found based on the soil characteristics at the research site. The slope is considered dangerous after being given an earthquake load of 1.044; according to the results of the safety factor value in the existing condition, sheet pile strengthening is required. The slope has been reinforced with sheet piles and is now in a safe state of 1,940Keywords : Slope stability, safety factor, sheet pile.
