汶川地震对绵阳地区桥梁的损伤和应急处治
|
摘要
汶川地震造成绵阳地区市政、公路桥梁发生不同程度的损伤.通过对桥梁结构进行灾后应急检查,掌握结构现状及其损坏情况,对灾后"保通"和防止次生灾害发生具有重要意义.分别以北川夏禹大桥、南坝大桥、安县安州大桥、平武高庄2#桥、江油太白桥、绵阳市机场桥和三汇高架桥为例,介绍了绵阳地区不同地点、不同类型桥梁的损伤状况和应急处治措施,对灾害及突发事故下桥梁损伤评估与修复具有参考价值.
Injuries were caused during Wenchuan Earthquake in differert degree to municipal and road bridges in Mianyang region.Through emergency inspections,the degree of damages of bridge structures is of great significance to keep access and prevent secondary disasters after the earthquake.In this paper,damages and emergency treatment of several different types of bridges in Mianyang region are introduced,such as Xiayu Bridge in Baichuan,Nanba Bridge,Gaozhuang 2nd Bridge in Anxian,Taibai Bridge in Jiangyou,Mianyang Airport Bridge and Sanhui Overpass.It is a reference for damage assessment of bridges after disaster or emergency.
