| 摘 要： | 汶川特大地震导致了青川县乔庄镇(主城区)遭遇了较为惨重的特大灾难.县城的恢复重建工作受到地震断裂、山体变形、强烈的余震活动等严重制约.尤其是地震断裂问题,更是对能否原址重建起决定性作用.在参考以往研究成果的基础上,结合实地调查,对该镇的地震断裂问题进行了评估,确定了青川-平武断裂(龙门山后山断裂主断裂之一)分三条分支断裂(北支断裂、中间断裂、南支断裂)穿过乔庄镇主城区的大致方位和走势,并且现场发现该三条分支断裂均发生了不同程度的地震破裂(如地表破裂,山体震裂等),已逐渐发展成为中强震的孕震构造.

| Abstract: | Wenchuan earthquake resulted in that Qiaozhuagn town of Qingchuan country sufferd more serious disaster.The Country's reconstruction was serioushy restricted by many issues such as the earthquake faults,the deformation of the mountain,and the strong aftershock.In particular,the earthquake fault problems played an decisive role in whether the countny was rebuilt in situ or not.In this pape,we assesed the earthquake faults about the Qiaozhuang town by adopting the method that conbining previous research and o... |
