Analisis Potensi Likuifaksi di Tapak Reaktor Daya Eksperimental Serpong

The phenomenon of changing the nature of the sediment from solid state to a liquid state caused by shear stress at the time of an alternating earthquake is called liquefaction. Liquefaction can cause severe damage. Liquefaction analysis aims to determine the potential for liquefaction at the site of RDE especially the reactor building. The analysis was done by simplified method by using Standard Penetration Test (SPT) data. From these data, then can be calculated Cyclic Stress Ratio (CSR), Cyclic Resistant Ratio (CRR) and Safety Factor (SF). Based on the calculation analysis, it is concluded that the reactor building area has a potentially liquefaction soil layer at depth of 2 to 6 meters and at depth 24 meters.
