摘要
杜公岭隧道从太行山区分水岭地带的碳酸盐岩类地层通过,地下水位埋深大于400 m。勘查和施工均无发现地下水的存在,因隧道开挖、建设使降雨入渗后在洞身聚集并与围岩共同作用,使洞体路基出现隆起、墙体衬砌开裂、滴渗水等,影响运营。就隧道特殊水文地质病害的变形机理与处治技术进行分析总结,对今后同类工程有借鉴指导作用。
Taking Dugongling tunnel as an example, this paper analyzed and summarized the deformation mechanism and treatment technology of tunnel special hydrogeological diseases, which had guiding reference for the similar engineering in the future.
