王子石隧道地质条件较复杂,为了减少工程隐患,使用地质雷达进行超前探测,查明了不良地质体的分布,对围岩类别进行了动态划分,并及时变更了施工方案。后经开挖验证,说明采用地质雷达探测掌子面前方的地质情况是可行的。
The geological conditions of Wangzi Shizhong Tunnel are complex. In order to reduce the project hidden danger, the geological radar is used to carry out advanced exploration. The distribution of the poor geological body is identified. The dynamic classification of the surrounding rock is carried out and the construction plan is changed in time. After excavation verification, indicating the use of geological radar to detect the face in front of the geology is feasible.
