| 摘 要： | 作为黔张常客运专线6座Ⅰ级高风险隧道之一，卧云界隧道受到涌突水严重威胁。通过对卧云界隧道汛期涌水量和降雨量进行相关分析，发现降雨不仅与隧道涌水具有高度相关性且在岩溶含水层的调节作用下存在滞后性，在此基础上建立降雨-涌水回归方程。结果表明:采用回归方程预测隧道涌水量具有简单、快速和精度高的优点，可为隧道在未来不同降雨条件下涌水量预测提供依据。

The Correlation Study between Rainfall and Water Inrush in Woyunjie Tunnel of Qianjiang-Zhangjiajie-Changde Passenger Line |

| Abstract: | As one of the six high risk tunnels of grade I in Qianjiang-Zhangjiajie-Changde passenger Line, the Woyunjie tunnel is seriously threatened by water inrush. Exploring the correlation analysis of water inrush and rainfall in flood season of Woyunjie tunnel, the water inrush is not only highly correlated with rainfall but also lagging behind under the regulation of karst aquifer. Based on this, a multiple linear regression equation of rainfall-inrush was established. The result shows that using multiple regression equation to predict tunnel water inrush was of simple, fast and high precision, which can provide the basis for water inrush forecast in tunnels under different rainfall conditions. |
