一、前言水坠坝的冲填土,是由含水量远大于流限的泥浆,经脱水固结使含水量低于流限逐渐形成的。实践表明,水坠坝施工期存在一个含水量大于流限的流态区,它是施工期产生滑坡的主要原因。通过固结计算,预先估算出施工期流态区的深度变化,对验算水坠坝施工期的坝坡稳定具有十分重要的意义。
I. Introduction Water fill the dam of red fill, by the water content is much larger than the flow limit of the mud, the water content of less than the flow rate of the formation of dehydration gradually formed. Practice shows that there is a fluid area with a water content greater than the flow limit during the construction period of the water drop dam, which is the main reason for the landslide during the construction period. Through consolidation calculation, it is estimated in advance that the change of the depth of the fluid regime during the construction period is of great significance for checking the dam slope stability during the construction period of the water drop dam.
