摘要
通过进行不同密实度条件下未加固与碎石桩加固可液化地基的振动台模型试验,对不同密实度下模型地基的宏观液化现象作了对比和分析,得出:砂土密实度越大,抗液化能力越强;在加固土中碎石桩形成排水通道,所以同一密实度下的加固土液化现象比未加固土推迟,这意味着碎石桩起到了很好的抗液化效果。
Based on the shaking table test on liquefiable sand rail with different density un-reinforced and reinforced by gravel pile, this paper compares and analyzes the macroscopical liquefaction behavior of model foundation with different density, and proves that the bigger the densi- ty of the sand .soil, the stronger the resisting liquefaction capability, in reinforced soil, gravel piles form draining alley, so compared with unreinforced, reinforced soil with the .same density liquefaction delays, it means gravel pile resist liquefaction effectively.
