摘　　要：本文根据大量模拟试验成果和野外观察资料,重点讨论了碳酸溶蚀效应、硫酸溶蚀效应以及几种混合液包括碳酸或硫酸加NaCl,MgCl_2及CaCl_2等对碳酸盐岩的混合溶蚀作用,并根据硫酸水溶蚀叠加于碳酸水溶蚀作用的研究,首次提出了碳酸盐岩叠加溶蚀效应的概念,指出由于叠加溶蚀效应的存在,使硫酸溶蚀明显较碳酸溶蚀强烈。Based on a vast amount of the simulated test data and the field observed materials. the chemical corrosion effects of carbonates rocks are studied. The corrosion effects with the car- bonic acid, sulfuric acid and several mixed solutions. including the carbonic acid or sulfuric acid plus NaCl, MgCl2 and CaCl2 are discussed in detail. respectively. According to the research re- sults of the piling-up processes of the sulfuric acid corrosion on the carbonic acid corrosion, the concept of the piling-up corrosion effect is firstly posed, and it is shown that because of this ef- fect. the sulfuric acid corrosion is obviously more intense than the carbonic acid corrosion. The influence of the different temperature ranges on the karst growth of carbonate rocks is also dis- cussed in the paper.
