真空负压对土体结构中水分运动影响试验探讨

Test of affect moisture motion in soil boy by vacuum negative pressure

本文通过模型试验,讨论了真空负压对土体结构中水分运动影响及快速排出水分的条件。针对本试验,把Darcy定律应用于非饱和带内水的运动,对非饱和渗流规律进行了初步讨论。

The paper discusses the influence of vacuum negative pressure to the moisture motion in soil boy and the conditions of speed drainage by means of model test. In view of this test, Darcy law is applied to the unsaturated and the internal water motion, the unsaturated seepage flow law is discussed.
