摘要
大连某港区高黏性超软吹填土采用常规真空预压和堆载预压处理效果不佳,为寻求解决方案,采用直排式真空预压法进行了室内模型试验,通过不同排水体、不同排水间距的室内对比试验和综合分析,得出采用直排式真空预压法加固高黏性超软吹填土时排水体间距起主导作用的结论。
It had poor effect to reinforce heavy clay recently reclaimed soil with routine vacuum preloading and surcharge preloading in Dalian port.The straight-line vacuum preloading method was adopted to carry on the laboratory model test for finding a solution.The result was that the drain spacing played a leading role to reinforce heavy clay recently reclaimed soil by straight-line vacuum preloading,through indoor comparison test and comprehensive analysis on different drainage materials and different drain spacings.
