| 摘 要： | 鉴于用普通强夯法加固饱和粉土、淤泥质粉土地基时功效低的现状 ,在分析强夯加固机理及特点的基础上 ,提出了用强夯碎石桩加固地基的方法 ,现场试验区强夯碎石桩复合地基的测试及荷载试验表明 ,该法不仅大幅度提高了饱和粉土地基承载能力和变形模量 ,而且扩大了强夯法的有效影响深度 ,消除了下卧砂层的液化特性 ,该法的工程应用结果表明 ,地基加固效果非常显著

| Abstract: | Seeing that inefficient effect of dynamic consolidation on saturated silt and having analyzed its mechanism and characterisics,a method of consolidating ground with dynamic compaction stone column has been put forward.Detecting and plate loading test on proving ground show that the method not only greatly enhances the bearing capacity and deformation modulus of the saturated silt,and increase the effective consolidation depth,but also eliminate the seismic liquefaction characteristics of substratum of sand.Application of the method in practical projects has proved that the consolidated result is very successful. |
