摘要
石灰岩和白云岩是碳酸盐岩主要类型,二者在岩溶发育强度方面具有明显的差异。文章结合三柳高速公路洞诺融江大桥勘察与施工中揭示的岩溶发育情况,分析了石灰岩和白云岩岩溶发育的程度及规律,得出石灰岩区岩溶发育要远强于白云岩分布区的初步结论,据此提出不同碳酸盐岩区地质勘察的初步对策。
The limestone and dolomite are the main types of carbonate rocks,both have significant differ-ences in karst development strength.Combined with the karst development situation disclosed from the sur-vey and construction of Dongnuo Rongjiang Bridge in Sanliu Expressway,this article analyzed the karst development extent and regularity of limestone and dolomite,obtained the preliminary conclusions that the karst development in limestone area is much stronger than the dolomite distribution area,whereby proposed the preliminary geological survey strategy for different carbonate areas.
