摘要
为研究真空预压过程中"土柱"的形成原因,采用粒子图像测速(PIV)技术观察了高含水率淤泥在真空预压下的变形特性,并结合孔隙水压力值以及排水量进行了综合分析。
In order to study the formation of "soil column"in the process of vacuum preloading,this paper adopts Particle Image Velocimetry( PIV) technology to observe the deformation characteristics of slurry with high water content under vacuum preloading. The PIV results were analyzed with pore water pressure and water discharge.
