摘要
由于回(吹)填成陆工程的面积一般较大,沉降值的计算准确性,对工程实际发生的工程量统计具有至关重要的影响,在实际工程中,常常发现地基沉降理论计算结果与实际沉降发生值差异较大的问题。因此,本文以泉州地区某回(吹)填工程为背景,分析总结了软土的变形特点,选取适当的沉降计算方法,并通过对工程实测沉降值和计算沉降值的对比分析,对该区域的地基沉降修正系数进行了修正,可以推广应用于其它相似工程。
Due to large area of land-forming project by backfilling(dredger-filling)in general,the accuracy of foundation settlement value has a vital influence on the statistics of actual engineering quantities.The engineering practice often shows obvious difference between the theoretical calculation results of foundation settlement and the actual subsidence value.Therefore,by studying a backfilling(dredger-filling)project in Quanzhou,analyzing and summarizing the deformation characteristics of soft soil,an appropriate settlement calculation method is selected,and the foundation settlement compensation coefficient for this area is corrected by comparing the actual settlement value with the calculated one.The research results can be extended to other similar projects.
