| 摘 要： | 以福建地区某饱和软土地基处理工程为例,根据具体地质条件及设计要求提出了真空联合堆载强夯的地基处理方法,通过施工过程中的沉降观测和施工结束后的第三方检测结果,特别是针对淤泥的含水量、孔隙比、压缩模量、静探Ps值和十字板剪切强度等参数处理前后的变化,说明该方法可以消除深厚软土的深层沉降及浅部形成较厚、强度较高的超固结硬壳层,从而可以满足工后沉降和承载力两方面的设计要求,并总结了沉降量计算的修正系数及与含水量等参数之间的对应关系,对该地区类似工程沉降估算具有明显的工程参考价值。

| Abstract: | Based on foundation treatment engineering for saturation soft soil of Fujian zone, Vacuum-Preloading-Dynamic Compaction Method was put forward. It fulfiled require of settlement and bearing capacity, Through foundation settlement observation, change of water content, void ratio, compression modulus, Ps value and shear vane test strength of silt soil in treatment fore and aft, farther sum-up relationship between water content and modify coefficient of settlement, practice proved remarkable reference value of engineering practice. |
