摘　　要：本文根据某高速公路隧道工程因暴雨引发的出口段岩溶涌水病害处治实例,阐述了隧道施工期间属枯水季节,未见异常发生,但经过雨季暴雨洗礼,造成隧道二次衬砌开裂直至崩开,最终形成涌水突泥。结合复杂地质条件,通过不同方案比选,充分考虑隧道结构安全、运营安全、节约成本和施工的可行性,最终采用洞内引排加泄水洞方案。该隧道岩溶水整治设计方案实施成功,为以后类似隧道设计、施工提供借鉴和教训。According to an example of the treatment of karst water inrush in the exit section caused by heavy rain in a highway tunnel project. There no abnormality occurs in the tunnel in the dry season, however, after the rainstorm in the rainy season, the secondary lining of the tunnel was cracked until it collapsed, eventually forming a water and mud. Combined with complex geological conditions, through different schemes, the tunnel structure safety, operational safety, cost saving and construction feasibility are fully considered, and finally the cave drainage and drainage tunnel scheme was adopted. The tunnel karst water remediation design plan was successfully implemented,providing lessons for similar tunnel design and construction in the future.
