ABSTRACT
This chapter discusses normally consolidation, overconsolidation and underconsolidation phenomena with emphasis on the normally and overconsolidated consolidation soil deposits. There are two general methods for prediction of settlement in landfill sites: Sower method and Yen and Scanlon method. These two methods are generally based on Terzaghi consolidation theory. The chapter also discusses the determination of vertical stress or pressure distribution in the soil mass caused by various types of surface loading, and the settlement analysis. Taylor has presented a method for determining the vertical stress distribution under a corner of a uniformly loaded rectangular area, using Westergaard's equation. Some additional information of settlement in various environmental conditions is added such as settlement analysis caused by dewatering, deep excavation, and decomposition at landfill sites. The purpose of settlement analysis of soil is to predict the magnitudes of settlements and times required for their occurrence.
