Effect of Replacement Layers on Bearing Capacity of Silty Clay Layer

Abstract

Soil conditions often pose significant challenges for soil and foundation engineers engaged in construction projects. In response to these challenges, researchers and engineers have dedicated considerable efforts to developing solutions to construct on weak soil layers. The replacement layer is one of the most efficient and effective methods to increase the ultimate bearing capacity under foundation. There are many advantages for replacement layer using such as its low cost, material availability, easy construction, quick construction time, simple testing procedures. There is a few of studies that determine the actual values of the ultimate bearing capacity of replacement layers. Most research and studies focus on theoretical and mathematical values of the ultimate bearing capacity for foundations replacement layers. The site selected for this study was located in Al-Qalyubia Governorate. The use of replacement layers in this study indicated that there is an increase in the ultimate bearing capacity for the studied site. In addition to that, engineering properties of replacement layer and natural soil condition plays a role in the ultimate bearing capacity values
