摘　　要：我国沿海及内陆分布着大量软土,这种软土具有天然含水量高、孔隙比大、渗透系数小、压缩系数大,抗剪强度低的特点。分析对软土路基加固前后土的各项指标、十字板剪切强度、孔隙水压力变化、堆载施荷进行分析,同时对固结度进行验算对比,可供真空联合堆载预压加固沿海软土地基参考。There is a large number of soft soil on China＇s coastal and inland, this soft soil with a natural high water content, void ratio, permeability coefficient, compression coefficient, weak shear capacity. By the vacuum preloading consolidation of soft soil foundation before and after experiment data, analysis of the changes of soil. The analysis of cross shear strength, observing the pressure of pore water, analysis of pile load, contrasting and checking on degree of consolidation, so expanding the application of vacuum combined with surcharge preloading.
