摘要
川东北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7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,所得出红层岩石经历长时间浸泡后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降低10%～20%。
Red beds and hydraulic projects are widely spread in the northeastern of Siehuan, there is an engineering significance studying on the time effect of the red rock water-rock interaction. Through experiment on six sets of samples of red beds collected from six reservoirs, we can obtain how softening coefficients of water-soaked red beds change over long time periods. Analyzing results show that the softening coefficient of the red beds can be reduced 10%-20% after 30-50 y socking period than those we generally get from lab.
