Abstract

A reinforced concrete type retaining wall was built in 2017 to strengthen the slope stability of Rembangan highway, Jember Regency, Indonesia. However, in 2018 the building was damage. Until now, the cause of the failure of the retaining wall is still unknown. This study aims to evaluate the causes of the failure of retaining walls and the stability of retaining walls on the slopes of the Rembangan highway, Jember Regency. The research methodology begins with primary and secondary data collection before processing the data using conventional methods and auxiliary software. After data processing, data analysis was carried out to find conclusions about the cause of the failure of the retaining wall. Result analysis showed that the retaining walls have a low level of safety factor for rolling stability, shear stability, and bearing capacity stability. In addition, the factor of safety for the bearing capacity of the group pile foundation as a reinforcement of retaining walls also shows a smaller value than that charged. In addition, the group pile foundation can suffer a total settlement of 1.28 m.

Abstract

The Santer Riverbank which is located in Panggul Melati Hamlet, Kepanjen Village, Gumukmas District, Jember Regency, East Java is still used by the community for agricultural land. This research was conducted to create safe agricultural land for the community. Landslides on this riverbank often occur because it is located on the edge of the river and has a steep slope. In the observation in 2022, there is a collapsed riverbank approximately 20 meters in front of the river embankment. To prevent a longer landslide area, the slopes on the river border are optimized so that residents can still use the land safely. The selected reinforcement is made based on the geometric conditions and the results of the SF value from modeling the existing conditions using the Geostudio program. Appropriate reinforcement based on geometric conditions and SF values ​​is a balancing method. close to the counterweight method, the geometric conditions are more optimal with the SF value increasing from 1.099 to 1.623
