Based on the hazard of Yaocuntang arch tunnel engineering in the highway from Jingdezheng to Huangshan,the paper illustrated the necessity of field monitoring measurement in tunnel construction. By site monitoring,such as ground settlement,clearance convergence,vault crown settlement and site observation, etc.
以景(德镇)婺(源)黄(山)高速公路姚村坦连拱隧道施工中出现的险情为例,结合地表沉降、洞内净空收敛及拱顶下沉进行观测及现场观察,针对隧道出口段围岩失稳导致中导洞右侧工字钢严重内敛现象进行了动态预报,从而为及时采取有效措施排除险情争取了时间,避免了重大事故的发生,以此进一步说明了监控量测在隧道修建过程中的必要性。
