超前地质预报在歌乐山隧道施工中的应用
|
摘要
隧道在施工中不可避免地会遇到诸如溶洞、突水、坍塌等常见的地质灾害,为了将地质灾害影响程度降到最低,施工前进行超前地质预报是十分必要的。详细介绍了TSP超前预测预报方法的原理,并以歌乐山隧道为例子,针对该隧道复杂的地质条件,施工过程中采用超前预测预报和红外线探测技术相结合,成功地预报了掌子面前方的地质信息以及隧道涌水情况,有效地指导了该隧道的安全施工。
The geological disaster,such as cave of karst,rushing water and collapse often occur in tunnel excavation.The forecast geological prediction is imperative before tunnel excavation to minimize geological disaster.Prediction and forecast technique as the further realization and supplement of tunnel prospect is important to subtract and prevent hazard.The TSP method was introduced,the external water pressure on lining and calculate model of line structure in tunnel is analyzed.The thesis cites Geleshan Tunnel,as an example,though the geologic term is complicated for abundant water in tunnel,the advanced geologic prediction and infrared ray methods are adopted in the tunnel construction,and are used to forecast the geologic information in tunnel facing frontage and rushing water in tunnel successfully.The forecast results are effective and guide the tunnel construction safety.
