The Stability of a Slope on Soft Soil Using the Hardening Soil Model

Abstract

AbstractThe development of reservoir construction does not always stand on with good carrying capacity soil, on the part of the existing soil layer with a soft to very soft constancy. About 10% or more of the total area in various regions in Indonesia or more precisely about 20 million hectares are soft-land which is composed of soft soil and moss soil. If we look at the problem of soft clay soil, which is very influential in the construction of the construction and its success, soil repair must be done first; therefore, the construction is not dented already the predetermined and intentional age. There is a soil repair solution that is minimal in cost but very good and effective for maintaining the stability of the landfill, namely by using a soil repair system with a retaining wall. The Finite Element Model is a method of research to solve a problem in a study or field of mathematics and physics. This method presents several parameter estimates for an amount of distinct scheme nodal constructions not known. The Hardening Soil Model Standard, or what can be abbreviated as (HS) is a continuation of the advanced soil behavior model. But the value or number of soil stiffness can be described, analyzed, and explained in more detail and accurately using stiffness. There is three dissimilar effort arduousness, called triaxial load stiffness (E50), triaxial loading stiffness (Eur), and one-way load stiffness (Eoed). In a convincing case, the Hardening Soil Model or (HS) method is proven to be more truthful and closer to field conditions. It can be seen and has been proven from numerous previous studies that show the Hardening Soil Model (HS) method is very distinctive and accurate by the outcomes of field testing. The charge of the safety factor or (SF) obtained after the investigation of slope constancy on soft soil using hardening soil modeling analysis is 1.59.KeywordsReservoir constructionSoil improvementHardening soil model
