碎石桩与强夯联合处理深厚填土场地试验研究

采用碎石桩与强夯法联合处理方法对某山区深厚填土场地进行了地基处理的试验及动力触探和对试验区各施工阶段的浅层载荷板试验，结果表明：碎石桩联合强夯地基处理能较大幅度地提高地基承载力并有效减少地基变形，对山区挖填土场地具有较好的适应性和较明显的经济效益，同时具有施工速度快、成本低等特点，尤其是在改善挖填方场地的力学性能方面效果显著。

The study of combined treatment of broken-stone pile/column and forced ramming for deep filling ground

Deep filling ground foundation treatment test in a certain mountainous area was performed by combined treatment of broken-stone column and forced ramming. The test results of dynamic pen- etration and shallow loading plate at each construction phase on the test site show that the bearing capacity of the foundation is improved dramatically with reduced foundation deformation. It is indica-ted that the combined treatment is of better adaptability and economic benefits for montainous and filling ground, digging that it has features of speedy construction and low cost and can improve the me- chanical properties of digging and filling ground.
