摘要
上海市临港地区吹填形成的陆域具有固结程度低、含水率高的性质,文中结合临港新城东港区实际案例,针对该区域土层特点、场地土层后期承载力及沉降控制要求,总结了吹填形成的软土地区可采用的多种地基处理方案,并进行多方案经济技术比较分析。该工程经比较分析最终确定采用小方桩复合地基处理方案,并通过单桩及多桩载荷板试验,验证了小方桩复合地基处理方案在工程中的适用性。
Theland reclamation in Lingangof Shanghai features the low consolidationdegree and high soil watercontent.Based on the project in Donggang district of Lingang,this paper summarizes several foundation treatment schemes that can be used in the land reclamation area with the soft soil.In addition,the economic and technical comparison ofthe schemesare analyzedin terms of the soil characteristics,the late soil bearing capacity,and settlement control requirements in this region.Finally,the small square pile composite foundation treatment scheme is used in this project,and the scheme is verified to be applicable through single pile and multi-pile load plate test.
