基于动态围岩分类的高速公路隧道围岩稳定性评价方法

Evaluation method of engineering construction stability for expressway tunnels based on dynamic classification of wall rock

针对高速公路隧道工程施工的特点,基于动态化的围岩分类,采用多种方法对隧道 围岩进行地质跟踪调查与预测.通过综合分析和优化处理上述信息,从而对公路隧道动态稳 定性进行评价,为高速路隧道工程稳定状况的评判提供了一种简单易行的方法.

According to the engineering construction characteristic of freeway tunnels, some methods were adopted to investigate and predict the geological condition of tunnel wall rock on the basis of dynamic wall rock classification. The information obtained by these methods was integratively analyzed and optimized so as to evaluate the dynamic stability of expressway tunnels. The results of practical application show that this evaluation method is simple and effective.
