石灰岩溶地质复杂，隧道施工中常见涌水突泥，地表坍陷，给施工与运营造成极大困难，整治也十分艰难，本文介绍多年来岩溶隧道施工的经验和教训，提出施工中的主要问题和应采取的对策。
补充资料：石灰岩
| 石灰岩 limestone 一种沉积碳酸岩。主要成分为方解石，有时含少量白云石，常混入石英、长石、云母和粘土矿物等。呈灰色或灰白色，性脆，硬度较小，用铁器易划出擦痕遇稀盐酸剧烈起泡。石灰岩按成因可划分为粒屑石灰岩（流水搬运、沉积形成）、生物骨架石灰岩和化学、生物化学石灰岩；按结构构造还可进一步细分，如竹叶状灰岩、鲕状灰岩、团块状灰岩等。石灰岩易溶蚀，故在石灰岩地区多形成石林和溶洞，称为喀斯特地形。它是烧制石灰和水泥的主要原料，也是制化肥和电石的原料，还被用于冶炼钢铁、制糖、陶瓷、玻璃、印刷等工业。
