摘要
目前碎石桩加固液化地基,其桩长一般穿透液化土层,本文通过地震时复合地基中超静定孔隙水压力的分布,认为在上部荷载和碎石桩排水作用的影响下,适当的预留一定厚度的液化土层也可达到消除液化的效果。
At present liquefactionnal soil is penetrated with the gravel columns to reinforce foundation. In this paper the pore-water pressure is studied in the non-penetrated liquefactional soil composite foundation during the earthquake, The conclusion shows in the effect of roadbed loading and the drainage of gravel piles,the liqefactional soil layer under gravel foundation can be set to eliminate liquefaction in same way.
