摘要
隧道涌水问题普遍存在,从隧道的施工到竣工运行都受其影响,特别是在南方岩溶地区尤为严重。根据勘察资料,走马岭隧道穿越可溶岩段(含断层破碎带)长1525m,占隧道总长的62%,极易发生隧道涌水事故。本文结合已开挖段隧道涌水的实时监测数据及前期工程勘察资料,对隧道涌水做出初步预测评价,为以后的施工提供依据。
The water intrusion is a common problem in tunnels, especially in southern karst area. It affects the whole process of tunnel construction and operation. According to the survey data,1525 -meter long（ 62% of total length of Zoumaling tunnel） karst sector （ including fault fracture zone ） is prone to water intrusion. This paper presented a preliminary prediction of water discharge, which may be caused by continued tunnel excavation, based on real - time discharge monitoring data of excavated tunnel and project surveys. The results provide guidelines for control of potential water intrusion.
