Dewatering Design and Discuss of Foundation Pit Excavation in Disposal Site with Contaminated Soil

Abstract

Foundation excavations support and dewatering method have been full-grown after years of development. However, during the excavation of polluted soil in special sites, dewatering scheme should not simply based on the experience and form of excavation but should be combined with the characteristics of contaminated sites so as to choose a reasonable dewatering method which meets the construction requirement of soil excavation on one hand and prevents the spread of contamination on the other hand. This paper design and analysis the dewatering of soil excavation in contaminated sites combined with specific project example.
