Bearing Capacity of Soft Clay Reinforced by Geotextile and Woven Bamboo

Abstract

Bearing capacity is a value used to determine the ability of soil to withstand the pressure and load of a construction. One of the methods to increase bearing capacity of soft clay soil is use geotextile material as reinforcement material. The use of geotextile requires high operational costs, so it needs alternative replacement materials with lower prices and easily available, one of which is woven bamboo. The soft clay soil came from Purwosuman Village, Sidoharjo District, Sragen Regency, Central Java with a planned water content of 60.00% and was saturated. The parameters studied were the effect of depth variation using a footing width ratio of 100 mm (B) there are 0.5B, 1B, 1.5B, and 2B accompanied by the width of reinforcement at each depth variation based on the theory of pressure distribution in the soil 2 Vertical: 1 Horizontal. This study conducted physical properties of soil and loading frame testing. Based on the test, the maximum load retained by the soil with reinforcement is greater than the soil without reinforcement by 2455.71%. From the results of the analyses reviewed, the greater the dimension of the reinforcement width, the greater the maximum load value that will be able to withstand.
