| 摘 要： | 以砂桩加固液化砂土的振动台试验为基础,通过测试加固与未加固模型土、同一桩距不同桩长下加固液化砂土的孔隙水压力,试验得出,未加固模型土埋深较浅的土层易液化,液化持续的时间较长,并随着深度的增加,液化程度有减小的趋势.

| Abstract: | Based on the shaking table test of liquefiable and soil improved by sand piles,and connected with the non-improved soil and improved soil and the pore water pressure of the intensified liquefiable sand soil with different length of piles,the paper proves the shallower layer of the unintensified model is easily liquefiable and the lasting time of the liquefation is a little longer.Besides,it is proved that the tendenly of the liquefation reduces as it get deeper. |
