摘要
注浆技术是通过隧道不良地质的常用方法之一。齐岳山隧道穿越多个断层地段,通过长、中、短超前地质预测预报技术,准确判定隧道围岩地质,施工中采用注浆回固技术通过断层。
Grouting reinforcement technique is one of usual methods adopted in fractured rocks.By long and medium term forecasting of geological conditions ahead of tunnel face,an accurate fault position can be determined.By means of grouting enforcement technique,tunnel excavation was carried out through several faults smoothly.
