Abstract

One proof of Kediri's progress is the construction of Doho Kediri International Airport which is expected to improve the economy and tourism in this city. The airport was built with the aim of improving connectivity and suppressing development disparities in southern East Java. The purpose of this study is to plan the construction of an earthquake-resistant which is gravity retaining wall on the Grogol Kediri Highway, Kediri Regency. . Planning is carried out at STA 3.8-4.0. ,  soil laboratory testing on samples obtained from the studied location.  Identification of the soil type, sliding angle, and weight of the soil volume at the site are needed to determine the planning of earthquake-resistant retaining walls. From the soil properties obtained, it can be determined that the land is included in the GC (Clayey Gravel) category With a shear angle of 28° and a weight of 1.463 gr/cm3. These results were used to calculate the dimensions and the stability of the retaining wall using the Coulomb method.  The retaining wall should have a peak body width of 1 meter, foundation width of 3.8 meters, foundation thickness of 1 meter, foundation depth of 1.04 meters, foot and heel width of 0.9 meters, height of 6 meters, and bottom body thickness of 2 meters. Based on stability calculations, the retaining wall is safe against overturning, shifting, and subsidence. Therefore, this retaining wall is a viable solution to prevent landslides and mitigate the negative impacts caused by them.
