震后公路隧道抢通技术

摘要

Emergency rescue research of road tunnel after earthquake, from tunnel portal to tunnel trunk, classify the situation according to the earthquake damage degree of tunnel and the destruction, simple clean tunnel hole, cross the gallery, damage treatment of tunnel portal ,the general situation of the emergency rescue measures ,collapse and deformation of grabbing, abnormal gushing and so on. We can put forward construction method by emergency treatment technology research. After the seismic disaster, emergency rescue measures of road tunnel after earthquake should be rapid and orderly, scientific, reliable, safe and applicable to ensure earthquake fast, scientific and effective post-disaster rehabilitation and reconstruction.%通过对震后公路隧道抢通技术的研究，从洞口洞门段到洞身段，根据地震对隧道破坏程度以及破坏类型进行分类，针对简单的隧道洞口清理、坑道穿越法、隧道洞门震害处理、一般情况洞内抢通、坍塌及变形抢通、异常涌水等情况进行应急处理技术研究，提出施工方法。保证地震灾害发生后，震害隧道在抢通工作上做到快速有序、科学可靠、安全适用，保证震区灾后恢复重建的快速、科学、有效进行。
