用室内试验方法确定深淤土地基预压方案

The Preloading Program of Deep Silt Soil Foundation Based on Indoor Test

通过对取自深淤土地基土样的室内模拟试验测得的土体的真空预压、堆载预压、真空堆载联合预压的物理力学性质变化、试样顶部沉降量和试样排水量变化指标进行比较,确定最优的深淤土地基的预压方案。

Based on indoor tests of the samples of the deep silt soil foundation, the variations of the physical and mechanical properties, the top settlements and the displacements of the soil samples are compared according to the vacuum preload, the cumulate preload and the associated preload, so the optimization preloading program is promulgated.
