| 摘 要： | 隧道作为地下建筑物,修建过程中不可避免地穿越不同水文地质体。涌水是隧道施工中常见的地质灾害,同时也是其它很多地质灾害的主要诱因之一,如突水、突泥、翻浆冒泥等等,对隧道工程的涌水量预测具有重要的实际意义。以雅安至泸沽高速公路大相岭泥巴山隧道为研究对象,以地质及水文地质分析原理为基础,建立数值模拟模型,对隧道涌水特征和涌水量进行预测。分析结果:隧道整体涌水量为41 366 m3/d,在主要断层处最大涌水量可达3 100 m3/d,在断层段施工,要提前采取措施严加防范,保证安全。

| Abstract: | Tunnel,as a underground building,will inevitably pass through different geological and hydrological masses during construction.Water burst is the common geological hazard in tunnel construction as well as one of the main causes of many other geological hazards,such as water inrush,mud burst and rising soil,so water burst prediction has important practical significance for tunnel engineering.In this paper,with Ya＇an-Lugu Expressway Daxiangling Libashan Tunnel as the subject,based on geological and hydrological analysis theory,numerical simulation model is established for prediction of water burst characteristics and amount in tunnel.The result shows that overall water burst is 41,366m3/d in tunnel and the maximum water burst reaches 3,100 m3/d in main fault.Therefore,for construction in fault section,measures shall be taken against water burst and ensure safety. |
