| 摘 要： | 吹填土地基沉降量较大,在规定的工期内如何控制好剩余沉降量（剩余主固结沉降和次固结沉降）一直是人们比较关心的问题。结合KNI项目2A岛围海吹填工程,采用巴隆（Barton）解结合太沙基（Terzaghi）一维固结理论推算排水板地基固结过程,通过在吹填土地基上打设塑料排水板来加速地基的固结过程,从而达到控制工后剩余沉降的目的,使之满足剩余沉降量的要求,详细研究了符合工程要求的塑料排水板的间距和深度。

| Abstract: | The settlement of dredgerfill foundation is usually large.It is important how to control the remaining settlement(the remaining primary consolidation settlement and secondary consolidation settlement) of dredgerfill foundation in the fixed period.In this paper,the Barron solution and Terzaghi one-dimensional consolidation theory are used to calculate the consolidation degree in the 2A Island reclamation engineering of KNI project.The plastic drains are set to accelerate the consolidation of foundation in order to reduce the residual settlement,which could meet the project requirement.The spacing and depth of the plastic drains that meet the project requirement are studied in detail. |
