摘　　要：针对吹填淤泥质土渗透性差和含水量较高等突出特点,依据真空井点降水的室内模型试验,采用单井点与群井不同形式的研究方法,对土层真空度、孔隙水压力以及其土工试验指标等进行了测试分析并总结了相应的变化规律,在此基础上考察其加固效果,并得出真空井点降水方法对于淤泥土有一定的加固作用。Taking the conspicuous traits of poor permeability and high water content for hydraulic-filled mucky soil into account,based on the vacuum dewatering model test of both single-well point and multi-well forms,some parameters such as vacuum degree,settlement,and pore water pressure are measured in the tests;moreover,the corresponding changing principles are investigated,including the reinforcing effect.Based on the tests,this vacuum well dewatering method can be used for the mucky soil.
