摘要
通过对某工程孔隙水压力及分层沉降资料的观测,分析采用真空-堆载联合预压法加固软土地基时土颗粒所受侧压力、渗流力和抗剪力的变化情况,从深层沉降和孔隙水压力变化方面分析了真空-堆载联合预压法对其加固效果的影响,为其在高速公路软土地基中的推广应用提供了依据和参考。
According to the pore water pressure and layered settlement observation, the change of seepage force, shear resistance and lateral soil pressure using vacuum-surcharge preloading method are studied.The effect of vacuumsurcharge preloading method on reinforcement is analysed from pore water pressure and layered settlement aspects.The research results could be taken as reference in soft-base treatment projects.
