摘要
超大断面岩溶性隧道的施工难度大、安全风险高,对施工技术提出了更高的要求。介绍了超前地质预报在该类隧道中的实际应用,通过对监测结果分析发现了地质异常地段,并及时调整支护技术参数,保障了隧道施工安全。
The construction is difficult in super large section karst tunnel and the safety risk is high, which puts higher requirements on the construction technology. The paper introduces the practical application of advanced geological prediction in such tunnels. Through the analysis of the monitoring results, the geological anomalies are discovered, and the technical parameters of the support are adjusted in time to ensure the safety of tunnel construction.
