| 摘 要： | 岩溶问题是碳酸盐岩地区进行工程建设必须面对的一个重要问题。文章首先分析了岩溶发育的基本条件、岩溶发育的机理。然后针对国家重点公路杭州至兰州线重庆巫山至奉节段大宁河特大桥桥址区两岸岩石试样进行了溶蚀试验研究。最后根据试验结果，得出了大桥桥址区两岸岩体的岩溶特征，指出了岩溶作用对大桥主墩桩基所构成的威胁以及需要进一步研究的问题。

| Abstract: | The Karst is a significant problem in the face of constructions in carbonate rock area. Firstly, the basic conditions and the growth mechanism of the Karst are discussed in this paper. Secondly, the experimental study on Karst erosion of rocks from an expressway great bridge location is introduced. Finally, based on the experimental study results, the Karat characteristics of rock masses at the banks of the bridge are obtained, and the effects of Karst on the main foundations of the bridge and the issues that must be paid more attention to are presented. |
