摘要
用砂岩、凝灰岩、页岩三类岩石试件进行长时间的饱水,对声波参数V_(?)、V_(?)和E_d随饱水时间的变化进行研究,得出了水对岩石各动态参数的作用有物理,化学两种效应,以及两种效应均具有初期快速效应和长期缓慢效应的特点;V_(?)、V_(?)、E_d的值尽管初期效应时有增减,但长期的结果都比风干状态的值低。
A long-term saturation was applied upon sand stone, tuff and shale samples soaked in water, for the purpose |in studying the correlation between sonic parameters Vp, Vs and Ed and the variation of saturation period. The study concludes that: ( 1 ) Water applies physical as well as chemical effects upon various dynamic parameters of rocks, while both effects feature in primary rapid reaction and long-term slow reaction; ( 2 ) Despite that the Vp, Vs and Ed values fluctuate at primary period, yet the long-term result shows that the values are all lower than those obtained at weather-dried condition.
