摘要

以龙湾燃煤电厂V-3区采用真空联合覆水预压处理软土地基工程为基础,利用大型通用有限元ABAQUS程序中的孔压边界条件模拟真空荷载,运用二维固结有限元进行模拟,分析其在真空联合覆水预压过程中的沉降情况以及超孔压分布情况,对类似工程有借鉴和指导意义。
This paper taking Longwan coal-fired power plant V-3 area by using vacuum and water-covered preloading treatment of soft soil foundation.It combines with the large general finite element program ABAQUS and uses the pore pressure boundary to simulation vacuum load by means of drainage plate unit subroutine.The use of two-dimensional consolidation finite element simulation,analysis of the vacuum preloading combined with water in the process of settlement and pore pressure distribution,for the later similar engineering having some guiding significance.
