| 摘 要： | 在地基处理中,碎石桩和强夯各有其优点,在进行特殊工艺组合:碎石桩加强夯,对于处理要求较高的饱和软弱原土基是非常有利的。碎石桩施工后桩间土的标贯试验、干密度、压缩模量、载荷试验表明:表部1.0～2.0m范围的土层的物理力学性质变差,2.0m以下的土层物理力学性质有所加强。强夯试验确定了强夯施工参数,夯后原土标贯试验、干密度、压缩模量、密实度检测和面层载荷试验表明地基土层的工程性质得到了显著提高,完全满足设计要求,起到了良好的处理效果。

| Abstract: | It is advantageous to treat saturated soft ground by gravel pile and dynamic compaction. The surface layer soil quality is low, and the lower soil is high, according to SPT, dry density testing, compress modulus testing, load-settlement testing, after gravel pile working. The reasonable working parameter and working technique are defined. The result of stabilization is well acquired in according with checking. |
