Abstract
With the rapid pace of industrialization, structures are being designed and constructed in the flood plains of major rivers. In earthquake prone areas, a fundamental issue in the design and construction of structures on saturated sandy soils is weather or not the design earthquake could initiate liquefaction in the form of lateral spreading, sand boils, settlement, or cracking. Many different methods, including vibrocompaction, deep dynamic compaction, compaction piles, geopiers, deep mixing, vibratory probes, displacement/compaction grout, etc., have been used to reduce the liquefaction potential at various sites. Use of vibrocompaction to densify cohesionless soil is becoming more common and cost effective. For projects in the New Madrid seismic zone (NMSZ) another challenge to perform site specific analysis is the lack of recorded ground motions. Therefore, synthetic time histories need to be generated using the attenuation models applicable to the region. This paper provides details about a site specific study performed for a site in the bootheel area of Missouri, and results of liquefactions analysis and ground modification achieved using vibrocompaction.
