Abstract

Abstract: Shenzhen Airport 110/10KV central substation was constructed within a reclaimed land. The site has an average muck thickness of 9.5 meters. The mucky soils have characteristics of high water content, high compressibility, low shear strength and in an underconsolidated state under the fill soil loading condition. The site was improved with surcharging and prefabricated vertical drains method. This paper presented the geotechnical monitoring results during the construction and surcharging period.

Key words: Surcharge Preloading, Prefabricated Vertical Drain, Ground Improvement, Settlement,Monitoring, Shenzhen Airport
