Gambaran Sifat Fisik Dan Mekanik Tanah Di Kecamatan Kauman Kabupaten Tulungagung

Abstract

The landslide disaster in Kauman District, Tulungagung Regency, East Java, resulted in various adverse impacts on community activities and the environment. The purpose of this study was to determine the classification of soil in the area. The methods used were atterberg limit testing, sieve analysis, compaction and shear strength. Soil samples were taken from the location of the former landslide and then tested at the Kadiri University Civil Engineering Laboratory. The research results on the liquid limit test obtained a value of 60.815%. The plastic limit test obtained a value of 32.24%. The sieve analysis test obtained the results for soil type SW, and the soil compaction test obtained an optimum water content value of 34.93% and dry unit weight maximum of 1.38 gr/cm 3 . Soil shear strength testing obtained a cohesion value of 2.532 Kpa and a shear angle value of 17.391 degrees, and it can be concluded that the soil is prone to landslides, so a special design is needed on the slope related to the slope of the slope and the model of retaining walls to prevent landslides.
