| 摘 要： | 为探讨降低潮湿多雨地区饱和过湿土含水量的方法及效果,通过室内模型试验,对真空预压排水法和电渗排水法的降水效果进行了对比分析.试验结果表明:2种方法都能有效降低饱和过湿土的含水量,达到排水固结效果,但土样中含水量降低程度的空间分布都存在不均匀性;采用真空预压法时,上下各层的含水量变化不大,固结效果相对较均匀. |

| Abstract: | In order to probe into the approaches and effects of reducing the water content in saturated over-wet soils in moist and rainy areas,the water drainage effects of the vacuum preloading method and electro-osmosis method were compared via indoor model tests.The result indicates that the both methods can effectively reduce water contents in saturated over-wet soils and obtain the desired effects of drainage and consolidation,but there exists inhomogeneity in the spatial distribution of water-reducing content w... |
