以马头山组(K_2m)、妥甸组(J_3t)和禄丰组(J_1l)紫色泥岩为研究对象,从水热相互作用泥岩的程度进行试验设计,分析了7种处理下3种泥岩崩解的差异性,结果表明:J_3t的崩解速率明显大于K_2m和J_1l,不同处理下紫色泥岩的崩解速率差异较大。运用聚类分析把3种泥岩7种处理下的崩解速率分为3类,3个类群间的崩解速率差异显著,引起3个类群间泥岩崩解速率差异显著的因素主要是泥岩的饱和泡水和泡水后存在较大的温差变化。其中饱和组崩解速率大于表面浸湿组,大温差组大于小温差或恒温组。特别是温差变化中冰劈作用的存在,引起了泥岩的快速崩解。揭示了水作用对崩解的影响大于热作用,温差的存在有利于母岩崩解。通过对三种紫色泥岩的粘土矿物组成、Saf值(J_1l(2.67)>K_2m(2.50)>J_3t(2.45))、ba值和成熟度(J_3t(0.87、15.42)>K_2m(0.85、11.46)>J_1l(0.50、7.03))的分析,表明J_3t最容易崩解,其次是K_2m和J_1l。 |

It was studied that the disintegration characteristics of purple mudstone from the Matoushan group (K_2m), the Tuodian group (J_3t) and the Lufeng group (J_1l), Yunnan Province of Southern China. The experiment was designed according to the interaction degree between hydrothermal and mudstone. The disintegration differences of 3 mudstones were analyzed in 7 treatments. The results showed that the disintegration rate of J_3t was higher than K_2m and J_1l. The disintegration rate of purple mudstone under different treatments had great difference. The main factors caused the significant difference of 3 groups were that mudstone was soaked and there was a big change of temperature difference after parent rock was soaked. Especially, the existence of frost wedging brought the quick disintegration of mudstones parent rock. It discovered that the water made a more important contribution than temperature in the process of rocks disintegration, and the change of temperature could promote the disintegration. By the clay mineral composition, Saf value (J_1l (2.67) > K_2m (2.50) > J_3t (2.45)), ba value and maturity (J_3t (0.87, 15.42) > K_2m (0.85, 11.46) > J_1l (0.50, 7.03)) analysis of 3 mudstones, these weathering indictors showed that J_3t was most easily disintegration, followed by K_2m and J_1l. Using the cluster analysis, the disintegration rates of 3 mudstones in the 7 treatments were divided into 3 groups. There was significant difference in the disintegration rates of 3 groups. |
