Liquefaction potentials analysis of sandy gravel on the sediment deposit of the Serpong formation

Abstract

Experimental Power Reactor Design in Serpong has been completed consisting of 4 (four) buildings, namely reactor buildings, supporting reactors buildings, switchgear buildings, and turbine buildings which are the main building of RDE power plants. Soil testing series has been carried out and delivered a number of data on sediment deposit formation which in its surface area is a sandy gravel soil layer and has the potential for liquefaction. Several analyses were carried out to test the liquefaction potential including surface sediment vulnerability analysis, grain size distribution analysis, liquefaction safety factor analysis, and liquefaction index analysis. The results show the level of vulnerability of the Serpong formation liquefaction in the medium category and there is a zone that has a high potential for liquefaction at DH-16 and DH-17.
