| 摘 要： | 在硫酸盐岩和碳酸盐岩混合建造地区，硫酸盐岩的溶蚀对岩溶的产生有着重要影响，对于某些岩溶现象和地质灾害的解释，必须考虑硫酸盐岩岩溶的影响，对硫酸盐岩的溶蚀机理及其影响因素的研究就显得尤为重要，本文采用室内实验模拟的方法，根据岩溶发育的影响因素，研究了硫酸盐岩的溶蚀机理。研究认为，硫酸盐岩溶蚀发育的条件不同于碳酸盐岩，即在水与硫酸盐岩体系内即使没有CO2的参与，水对硫酸盐岩仍具侵蚀性；硫酸盐岩溶蚀的发育不但与其本身的固有特性有关外，还与岩石所处的环境因素有关。

| Abstract: | Sulphate corrosion plays an important role on karst in carbonate sulphate formation although more attention focuses on the carbonate corrosion. Thus, it should be considered the effects of sulphate karst when we study some geological hazards caused by karst. A few works, however, take into account the mechanism of sulphate corrosion and therefore need to further study. The purpose of present work is to study the mechanism of sulphate karst and its influence factors by laboratory experiments. The results suggest that the condition of sulphate karst development is different from that of the carbonate karst, i. e. the water is corrosive in H 2O sulphate system even though there is no CO 2 in the system. Besides the influence of lithological characters, sulphate karst is also affected by environmental factors. |
