Analysis of Bearing Capacity of Spun Pile Foundation in Lamong River Flood Control Embankment Construction Project in Gresik District

Abstract

The construction of a flood control embankment on the Lamong River, Gresik, requires a strong and stable foundation to cope with significant loads and water pressure. The purpose of this research is to analyze the bearing capacity of the spoon pile foundation used in the project. The methods used include geotechnical analysis through field penetration testing (SPT) and laboratory testing of project site soil samples. Analysis of test data to determine the bearing capacity of the soil and the bearing capacity of the pile foundation. Taken as a reference for the calculation of the pile bearing capacity of the S2 results the total bearing capacity of the pile = 67.984 kg. and also taken as a reference from the results of BH-1 and BH-2 the total bearing capacity of the pile = 65.36 kg. The results of this study indicate that the spoon pile foundation with a depth of 24 m is able to withstand the construction load. Including being able to withstand the maximum load that occurs during flooding. Furthermore, the slope stability was evaluated and the foundation system was found to be safe enough against possible structural failure. Therefore, the use of spoon pile foundation in the flood control embankment construction project at Lamong River in Gresik district is recommended as an effective solution to improve the durability and safety of the building against flood risk.
