Abstract

This chapter provides an overview of the topics in soil mechanics that are relevant to soft clay engineering and ground improvement. An assessment of vertical stress increase due to external loads is a key point in soft clay and ground improvement designs. The vertical normal stress at a depth below a long embankment along the centerline could be assessed using influence factors proposed by Osterberg, which is discussed in several soil mechanics books. As excess pore water pressure dissipates, the effective stress increases by the same magnitude until the additional load is fully transferred to the soil grains. A soil classification system is a systematic way to group soils of similar behavior and describe soils without any ambiguity. The person who identifies the soil at the site or the one who does the tests in the laboratory is often different to the one who carries out the designs and analysis.
