地震反射波法技术及其在隧道超前地质预报中的应用研究

Application of earthquake refracted wave method to geologyical prediction for tunneling

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。介绍反射波法的原理和沪蓉西主干线扁担垭隧道现场实际应用情况,预报结果印证该方法能够取得令人较为满意的效果。

The geological disaster, such as cave of karst, rushing water and collapse often occur in tunnel excavation. Therefore the geological prediction is imperative before tunnel excavation to minimize geological disaster. The refracted wave method was introduced, and the geologial prediction for Biandanya Tunnel of the Shanghai--Chengdu Expressway was given as an example. It was found that the predicted result is conformable with the actual situation.
