| 摘 要： | 龙泉山地区中生代红层分布广泛,水利工程较多,研究库区红层岩石水岩作用的时效性具有工程意义。通过对该地区4个水库采样点所采集的岩石样品进行室内软化系数的测定,得出红层岩石经库水长时间浸泡后软化系数及软化系数随年代的变化规律,结果显示红层经过30~50年水库浸泡后软化系数较目前在实验室测得的降低10%~20%。

| Abstract: | Mesozoic red bed occurs and hydraulic projects spread widely in the Longquan area. Studies of the time effect of water-rock interaction of red bed are of engineering significance. After testing the softening coefficient of the samples of red rocks from four reservoirs, we obtained the changing regularity of softening coefficients after a long period of water-rock interaction. The results indicate that the softening coefficient of the red rocks reduce by 10% to 20% after 30 to 50 years of water-rock interaction, which is of important significance on the stable recheck of the reservoir-slope. |
