【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。该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】 Using the way of vibro-replacement gravel piles,it gains a better effect in dealing with a sand liquefaction foundation.The liquefaction is reduced or eliminated depending on the extrusion soil body,draining decompression and absorption seism of the pile body together.Through the test of a small-scale shaking table model,this paper focuses on the theoretical analysis and the action of the draining decompression of reinforced gravel piles.The experiments show that gravel piles can be used in a reinforcing liquefaction foundation.By well anti-permeability effect,the gravel pile is obviously better than other ways.更多还原
