华蓥山隧道暴雨涌突水及其对隧道的影响

Rainstorm -Induced Sudden Water Inflow and Its Influence on Huayingshan Tunnel

本文根据当前水文地质研究的新观点和新思路,即地下水地质作用及地下水系形成演化的分析法,通过华蓥山隧道西口左洞的暴雨突水及有关区域水文地质资料的收集与整理,探讨了暴雨涌突水系的形成演化,进而分析了该暴雨涌突水系活动的特点,并预测了涌突水对隧道的影响。同时指出,若对现已形成的涌突水系不加研究和合理的治理,或在施工过程中处理不当,暴雨涌突水将成为严重影响隧道工程质量与威胁隧道安全的隐患。

In the light of the hydrogeological data of sudden water inflow occurred in the west portal section of left tube of Huayingshan Tunnel, the paper introduces the causes, evolution, characteristics and influence of rainstorm-induced sudden water inflow on the tunnel, and points out that the rainstorm - induced sudden water inflow will exert a great influence on the construction quality and threaten the stability of tunnel if the study and suitable treatments are not made during the construction.
