ABSTRACT To explore the impact of temperature difference (TD) on the disintegration of redbed softrock, three types of redbed rock, collected from Nanxiong Basin, were analyzed under three different treatments: TD, wetting and drying (WD), and TDWD-temperature difference and WD. To better understand the influence of different ranges of TD on disintegration during WD cycles, pH (hydrogen ion concentration) values, electrical conductivity (EC) values, and concentration of cations in leachate released during treatment were measured. The results show that no significant change can be observed under single TD treatment but that TD can increase the disintegration rate by accelerating the water–rock interaction. The effect of TD is more significant for rock with weak resistance to disintegration.

温差对红层软岩崩解作用的室内研究

摘要 为了探讨温差（TD）对红层软岩崩解的影响，从南雄盆地采集的三种红层岩在 TD、干湿（WD）和 TDWD-温差三种不同处理下进行了分析。和WD。为了更好地了解不同范围的 TD 对 WD 循环过程中崩解的影响，测量了 pH（氢离子浓度）值、电导率 (EC) 值和处理过程中释放的渗滤液中的阳离子浓度。结果表明，在单一TD处理下没有观察到显着变化，但TD可以通过加速水-岩相互作用来提高崩解速率。对于抗崩解能力较弱的岩石，TD的影响更为显着。
