Abstract

Efforts to improve slope stability have several methods that can be used, one of which is to use retaining wall construction. A retaining wall is a construction that functions to withstand lateral earth pressure generated by the soil behind the retaining wall. There are two types of retaining walls that are often found in the field, namely the gravity type and the cantilever type. This study aims to compare the use of the two types of retaining walls at various slope heights. The soil data used in this study is soil data at the Lio Salem Slope BTN location, Brebes Regency. The results showed that at a slope height of up to 7 m, the safety or stability value for the cantilever type was higher than for the gravity type, both for stability against bearing capacity collapse, overturning, and shearing.

Abstract

The Slawi city ring road is a road that connects several villages in the Tegal district, especially the Pangkah and Slawi sub-districts. This road is often passed by heavy vehicles such as trucks and other cars carrying goods, many motorized vehicles also pass on this road, especially students. With the volume of vehicles that are quite dense at certain hours and with minimal maintenance on road conditions, this causes a decrease in the quality of the road surface. With these problems, it is necessary to analyze the condition of road damage at STA 0+000 to STA 1+720. This study aims to determine the type and level of road damage using the Bina Marga 1990 method, determine the percentage value of each damage and calculate the priority order of the road as a reference for determining the repair program for the road. Data collection using the LHR survey is also needed to determine road condition values. Factors that cause road damage are the lack of routine maintenance on the road and the absence of drainage so that a lot of water stagnates during the rainy season which causes road damage to become more severe. The types of damage found on the Slawi City ring road are pothole damage, grain release, fatness and crocodile skin cracks.
