| 摘 要： | 隧道施工监控是隧道新奥法施工中重要的组成部分，如何分析、处理监测信息并判断围岩和隧道支护结构的工作状态，对优化设计和保障施工安全有重要作用。本文以安基山隧道工程为依托，通过位移收敛监控量测以及时了解隧道开挖后的围岩变化情况，及时预见事故和险情，根据围岩位移收敛速率曲线形态特征推断围岩稳定程度，为二次衬砌的施作时间提供依据。

| Abstract: | Displacement monitoring is an important component of New Austrian Method in tunnel engineering. Analysis of monitoring information and state judgment of surrounding rock and supporting structure are very important to optimization design and construction safety. The displacement convergence was monitored in the tunnel of Anji Mountain to acquaint the change of surrounding rock after excavation and forecast danger in time. The stability of surrounding rock can be judged by analysis on characteristic of velocity curve in displacement convergence. It can also provide evidence for construction time of secondary lining. |
