【摘要】 振冲碎石桩处理砂土液化地基,通过挤密土体以及依靠桩体的排水减压和桩体减震共同作用来减轻或消除砂土液化的影响,取得较好的效果。本文利用小型振动台模型试验,重点研究碎石桩加固后的排水减压作用和理论分析。试验表明采用碎石桩加固可液化砂土,由于其良好的透水性抗液化效果明显优于其它方案。更多还原

【Abstract】 In vibro-replacement stone column foundation to deal with sand liquefaction,through pushes the dense soil body as well as the dependence pile body draining water decompression and the pile body absorption of shock does together uses for the influence which reduces or eliminates soil liquefaction,obtains the good effect.In this paper,use of small-scale shaking table model test,focuses on the rubble pile after the decompression drainage role and theoretical analysis. Experiments show that the use of gravel can be liquefied sand pile,because of its good anti-permeability effects of liquefaction are better than other programs.更多还原
