在役隧道震害检测与评估

为了解公路山岭隧道因强震受损情况,避免次生灾害的发生,对隧道净空、衬砌厚度、衬砌强度、裂缝及渗漏水情况进行了全面的调查和检测,依据现行规范对其进行了技术状况评估。结果表明:隧道衬砌、路面、洞门结构及机电设施良好,可确保隧道安全运营;但需采取一定的堵漏措施,防止地下水渗流对隧道的影响。

Testing and Evaluation of Seismic Hazard of In-Service Tunnel

In order to know the damage situation of strong shock and avoid secondary disaster,the headroom of tunnel,the condition about thickness and intensity of lining,the cracks and water leakage are surveyed and tested roundly,and the technical status is evaluated according to current criterions.The results show that the lining,pavement,portal structure and electromechanical equipment are all right for ensuring the safe operation of tunnel,but some plugging measures should be applied to avoid the influence of groundwater seepage on tunnel.
