Case Study of Ground Improvement to Qianhai Reclamation Area, Qianhai Bay, Shenzhen

This paper mainly introduces the design and construction of ground improvement in the Qianhai reclamation area, Qianhai Bay, Shenzhen, China. The seabed water level in the reclamation area is about 2.0 to 3.0 m, the thickness of the soft soil ranges from 6.0 to 15.0 m, and the treated reclamation area is about 7.62 km². Different soft ground improvement methods were adopted to treat the marine soft soil and backfilled soil to satisfy the requirements of various development purposes, such as: (1) explosion method for the sea embankment construction; (2) riprapping used to strengthen dikes; (3) fill-surcharge preloading and vacuum-surcharge preloading used to treat the soft clayey soils, dynamic compaction, vibro-stone (sand) columns, deep cement mixing; and, (4) also used to treat road foundation soils. The features, advantages and limitations of these methods are discussed in the paper.
