: Removing the risk of soil liquefaction during earthquakes or major vibrations. Major Categories of Improvement Methods 1. Mechanical Modification (Soil Densification)

These techniques use physical force to reduce air voids and increase soil density. Soil Improvement and Ground Modification Methods Soil improvement and ground modification methods

: Restricting or promoting groundwater flow depending on project needs. : Removing the risk of soil liquefaction during

: Enhancing bearing capacity and shear strength to support heavier loads. Soil improvement and ground modification methods

Soil improvement and ground modification involve altering the engineering properties of soil to enhance its performance for construction. These methods convert "marginal" or problematic soils—such as those prone to liquefaction, excessive settlement, or low bearing capacity—into stable foundations for structures like buildings, highways, and dams. Core Engineering Objectives The primary goals of modifying ground conditions include:

: Minimizing future settlement and volume instability (shrinking/swelling).
