Stability Analysis of Flood Control Parapet Wall in Lamongan River, Kedanyang Village, Gresik District

Abstract

Floods are natural disasters that occur due to continuous rainfall which can cause significant damage to communities, especially communities in downstream areas. To overcome the problem of flooding, embankments need to be built to prevent river overflows so as not to damage the property of the surrounding community. 

This research focuses on analyzing the stability of embankments in Kedanyang Village, Kebomas District, Gresik Regency, which considers differences in foundation designs from previous projects. Quantitative research methods are used to test the resistance of parapet walls to rolling loads and vertical loads. The results show that the parapet wall is stable against overturning loads with a value of 181,420.8 kg, smaller than the pile bearing capacity of 267,976 kg, and stable against vertical loads with a pile bearing capacity of 130,720 kg, which can withstand a parapet wall load of 55,680 kg.
