| 摘 要： | 分析了真空预压中地下水位变化的研究现状,指出用实测数据进行研究存在误区。在定义地下水位线的基础上,通过土体结构的微观解说,分析了水位变化的机理。得出堆载预压地下水位线不变,而真空预压在考虑地下水补给的情况下,有下降和不变两种可能。提出了主动渗流和被动渗流以及固结渗流和非固结渗流的新概念。

| Abstract: | The current situation of studies on groundwater level in vacuum preloading is analyzed. It is pointed out that unreasonable to research simply by using the results of field monitor. The mechanism of the groundwater level changing is analyzed by explaining the microcosmic structure of the soil on the basis of defining the groundwater level. It is concluded that the groundwater level is not movable simply by preloading, and it may decline or remain immovable in vacuum preloading when considering the supply of the groundwater of the neighborhood. The conceptions of the initiative seepage, passiveness seepage, consolidation seepage and non - consolidation seepage are defined. |
