An Analysis of Single Slope Stability at Pemenang Road Using Bishop Method

Abstract

One of the roads in the Pemenang District, West Lombok Regency, which connects the districts in West Nusa Tenggara, is the Pusuk highway. Due to the area’s considerably steep slope, landslides frequently occur there as much as the rainy season comes. Almost all incidents of abruptly raising slopes, with or without warning indications preceding them, can result in landslides. This is a critical feature for proper handling. Using the survey method, especially the field survey, the researcher used Bishop Method with a 2D SLIDE application model to analyse the data. It was designed to evaluate the magnitude of landslide vulnerability. The safety factor study yielded a score of 0.889 <1.25, indicating that the slope falls under the heading of risky slopes.
