| 摘 要： | 本文对某电站24个钻孔151段压水试验资料进行了数理统计和正交多项式分析,得出了单位吸水量ω值随深度变化的曲线方程式,借此可计算坝基ω值随深度变化的趋势,帷幕灌浆深度和其它一些有关问题。这对合理布置钻探进尺,预估帷幕深度和节省费用都是有益的。

The Velticle Polynomial Expressions of Water Absorption Perunit With Depth Alternation |
| |
| Abstract: | This article, having made an analysis to the experimental data of 151 segment pressing water in 24 bores of a power plant in mathematical statistics and verticle polynomial expressions, presents a curve equation indicating the chageof the value ω (water absorption per unit) in accerdance with depth by means of which a calcutatou can be done in the changing tendency of the value of a dam base at different depths, the curtain grouting depth and some relevant prohlems This will be of great help in rationally distributing drilling depths preestimating the curtain depth and saving money in project, |
