阳阳高速公路鹅步岭隧道病害监测

Disease Monitoring to E-Bu-Ling Tunnel of Yang-yang Expressway

营运公路隧道病害以衬砌裂缝、渗漏、隧道结构稳定性为养护工作的难点,尤其是工程地质条件复杂和浅埋、偏压等地段的隧道结构稳定性是隧道养护的关键工作。结合鹅步岭隧道近3年的应力应变监测、裂缝监测和衬砌周边收敛监测,以该隧道病害监测发展情况,预判隧道结构的稳定性,为养护及维修加固处治提供参考依据。

As highway tunnel diseases of lining crack, seepage, stability of the tunnel structure have become diffi-culties for maintenance, especially the stability of tunnel structure under complicated engineering geological condi-tions and within shallow-buried and bias location. Being combined with nearly three years of monitoring for stress and strain, crack and lining limit of E-Bu-Ling Tunnel, being based on the development situation of disease moni-toring, the structure stability of the tunnel has been determined, which could provide reference basis for mainte-nance and strengthening measures of the tunnel.
