Analisa Stabilitas Lereng Terhadap Ruas Jalan Hatalae-Kilang Kota Ambon STA 1+300 - 1+360

Abstract

Maluku Province, Ambon City has an area of 359.45 km2 which is not spared from various types of natural disasters, one of which is landslides, especially on the highway network which is one of the most important land transportation infrastructure and is an element of regional development in Maluku Province. Hatalae road, Sirimau District, Ambon City, at kilometer 1 on the left side of the road there is a cliff area with a length of 60 m and a height of 15 m without cliff retaining buildings so that in certain situations such as rain can disrupt road user activities due to fears of landslides, so it is necessary to analyze the stability of the slope. Data analysis in this study includes: analysis of measuring data and soil investigation. Avalanches can occur on the road section of the Hatalae - Refinery Area of Ambon City caused by cutting soil at the foot of the slope as transportation utilization, dynamic loads caused by wind blowing, lateral pressure and decreasing soil shear angles. Based on safety factor analysis using the Fellenius Method SF=1.9 soil movement occurs frequently and the Simplified Bishop Method SF=1.7 soil movement is rare, meaning that the slope is already in stable condition
