摘要
本文通过对某工程孔隙水压力及水平位移资料的观测 ,分析了通过真空—堆载联合预压法加固软上地基 ,土颗粒所受侧压力、渗流力、抗剪力的变化 ,揭示了真空—堆载联合预压法在地基水平位移方面的相互作用 .
Based on the local pore water pressure and the lateral deformation from field vacuum-surcharge preloading instruction,seepage force,shear resistance and lateral soil pressure are studied.The mechanism of lateral deformation is revealed under the interaction of vacuum-surcharge preloading method.Some conclusions are drawn:seepage force caused by vacuum preloding method counteracts the force caused by preloading method,which is beneficial to the foundation's stability;groundwater table affects the reinforcement;vacuum-surcharge preloading method hazardsthe buildings’stability;groundwater table affects the reinforcement ;vacuum-surcharge preloading method hazards the buildings'stability in circumference.
