上海临港地区软土地基处理应用实例

An Example of Soft Soil Foundation Treatment in Lingang Area in Shanghai

城市外围促淤造地是提高城市土地利用率的1种有效方法。在上海软土地区涉及一系列如吹填土地基承载力、地基加固后的承载力、大面积填土引起的地基变形预测等岩土工程问题。通过岩土工程治理,针对不同土性既有成熟技术的集成应用,也提出了改良与创新方法,获得了技术和经济上的成功,为类似大面积围海造田开发提供了良好借鉴作用。

The method of land creation by silt in urban periphery is regarded as an effective way to improve urban land use efficiency.A series of geotechnical engineering problems are the keys such as dredger fill foundation bearing capacity,the bearing capacity after foundation strengthening and foundation deformation prediction by large area filling,etc.in Shanghai soft soil area.Through geotechnical engineering treatment,aiming at the integrated application of existing mature technologies of different soil properties,improvement & innovation methods are proposed with the double success of technology and economy,which can provide references for similar large area land creation from the sea projects.
