State-of-the-practice mitigation measures for collapsible soil sites

Mitigative alternatives for collapsible soil sites are reviewed considering shallow, as well as deep, collapsible soil deposits. In the case of deep soil deposits the overburden pressures alone are adequate to generate significant collapse settlement; for shallow deposits the structural loads are the more significant contributor to the collapse. Some of the case histories reported relate to site improvements or foundation design modifications which occur after construction of the facility, whereas other case histories relate to mitigating measures taken before construction.
