摘要
文章针对岩溶隧道的地质特征及病害类型,在介绍地质超前预报的内容、技术特点及所用方法优缺点的基础上,提出了综合地质超前预报法,并结合广西靖西至那坡高速公路各固隧道施工实例,探讨了该方法的使用效果。实践证明,该方法能全面、及时、准确地预报隧道掌子面前方地质情况。
Regarding the geological characteristics and disease type of karst tunnels, based on the introduction of content, technical characteristics and advantages/disadvantages of the used method of geological advanced forecast,the article proposed the comprehensive geological advanced prediction method,and combined with the construction case of Gegu Tunnel in Guangxi Jingxi-Napo Expressway, it discussed the application effect of the method. The practice proved that this method can comprehensively, timely and accurately predict the geological conditions front of tunnel face.
