摘　　要：以大亚湾石化区填海工程中吹填淤泥地基加固工程为背景,探讨真空预压法和静动力排水固结法两种地基处理方法在相同面积、同一吹填口吹入淤泥的H1和I1地块中应用的情况。同时从地基沉降值、土体的物理力学性质、原位测试指标等方面,分析了真空预压法在H1地块、静动力排水固结法在I1地块的加固效果,比较了两种方法的优缺点。结果表明,静动力排水固结法更适用于该区域的吹填淤泥地基加固。The hydraulic fill mud foundation treated by the vacuum preloading method and the static & dynamic drainage consolidation method is applied in H1 and I1 blocks in Daya Bay,which have the same acreage.Settlement of foundation,physical behaviors of soil,and results of field tests on H1 ground by the vacuum preloading method and I1 ground by the static & dynamic drainage consolidation method are analyzed,and the merit and demerit of these two methods are compared in the strengthening effect of foundation.The results indicate that the static & dynamic drainage consolidation method is more suitable for the hydraulic fill mud foundation treatment in this area.
