Abstract

The construction of Eka Hospital BSD as a high-rise building hospital faces challenges, especially related to soil stability due to dewatering work. The purpose of this study is to analyze the stability of soil retaining walls due to dewatering work. The research method used was the calculation of the stability of the retaining wall and the calculation of the discharge of seepage water & dewatering pumps, then simulated the geometry modeling in the plaxis. The research data used are secondary data in the form of dewatering monitoring data, inclinometer monitoring data, boring-log test and shop drawing for the construction of Eka Hospital BSD. The results of the analysis of the stability of the retaining wall in manual calculations showed that the safety factor on the retaining wall was 3.41 (SF overturning); 3.61 (sliding SF); 5.69 (SF bearing capacity). The groundwater discharge that seeps into the excavation is 1038 m3/day, and the volume of water that must be pumped is 6367.7844 m3 with 1 pump with a capacity of 1000 m3/day requiring a drain time of 7 days. The plaxis output due to the dewatering work showed a global SF 2.5 result with a decrease in groundwater level of 28.17 m. The maximum deformation results were at 20,394 mm at the monitoring reading and 17 mm at the Plaxis output.
