基于时间序列的中坝隧道涌水分析

隧道涌水是四川岩溶地区隧道开挖过程的重大影响因素之一,决定隧道的顺利施工与否.以中坝隧道为例,通过工程地质勘查和渗流管道调查,结合降雨量与涌水量的时间序列分析,更加准确地判断富水溶腔的连通性,阐述该类隧道涌水形成机理,有效地为预测和解决隧道涌水问题提供借鉴.

Analysis of Zhongba Tunnel Gushing Based on Time Series

The tunnel gushing is one of the major influencing factors of tunnel excavation in karst areas of Sichuan, which decides whether the construction of the tunnel is successful or not. This paper takes Zhong- ba tunnel from Xuyong to Dacun railway as an example. By conducting engineering geology exploration and seepage pipes survey, and combining time series analysis of the rainfall amount and water inflow amount, we can judge more accurately the connectivity of rich aqueous chambers. This paper discusses such kind of tunnel gushing formation mechanism, which effectively provides a reference for predicting and solving the problem of tunnel gushing.
