摘要
以温州丁山垦区的吹填淤泥真空预压加固处理工程为例,基于现场试验和数值模拟,对无砂垫层真空预压法和传统的有砂垫层真空预压法从表面沉降、分层沉降、孔隙水压力、固结度、静力触探、十字板强度及部分土体物理力学参数等方面对加固效果进行了对比分析。结果表明,两者加固效果接近,无砂垫层真空预压法可用于代替传统的有砂垫层真空预压法。
On the background of hydraulic mud fill reinforcement project with vacuum preloading in Dingshan reclamation area of Wenzhou city,based on the field test and numerical simulation,comparative analysis of strengthening effects between non-sand cushion vacuum preloading and traditional one is implemented from the aspects of surface settlement,layered settlement,pore water pressure,degree of consolidation,cone penetration test,vane test and some physical and mechanical parameters of the soil.The results indicate that the strengthening effects of these two methods are similar and non-sand cushion vacuum preloading can take place of the traditional method.
