摘　　要：文中开展一系列缩尺模型试验,选用福建福州地区软土作为试验土样,以袋装砂井布置密度和袋装砂井单双侧排水为试验变量,研究土体的沉降量、含水率随时间的变化关系以及固结后土的抗剪强度。In this study,the soft soil in Fuzhou area of Fujian Province is selected as the test soil sample by using the scale model test.Taking the layout density of the sand well and the single and double sides drainage of the sand well as the test variables,the relationship between the settlement,the water content of the soil with time and the shear strength of the soil after consolidation are studied.

关 键 词：袋装砂井 双侧排水 含水率 沉降
