摘要

强震后高烈度艰险山区抢通交通生命线是一个难度极大的工程。依托汶川特大地震汉清路九金段震害调查及抢通实地踏勘,对汉清路九金段震害及抢通处治技术进行了研究。研究结果表明:九金段主要受水毁影响,应注重对临河路基边坡的加固防护,提高抗冲刷能力,防止暴雨期泥石流改变河流形态而冲毁路基,并注重对道路有严重威胁的危岩的清理。对罕遇地震后高烈度艰险山区交通生命线的抢通具有借鉴意义。
        Rush-repairing and putting through the traffic lifelines after a highly intensive earthquake is a project of great difficulty.A study is made of the rush-repairing,putting-through and treating techniques for the Jiugeng Bridge-Jinyuzui Dam Section of Hanwang-Qingping Road in Wenchuan upon the basis of field-investigating the earthquake-caused damage and the rush-repairing-putting through project.The result of our research shows that the Jiugeng Bridge-Jinyuzui Dam Section is chiefly destroyed or damaged by floods,in which case strengthening the protection of the side slopes and roadbeds near rivers should be emphasized,the anti-washing capability should be improved to prevent mud-rock flow and landslide from changing river morphology and destroying the roadbeds during strong rainstorm.Clearing dangerous rocks and stones that threat the side slopes and roadbeds near rivers should also be stressed.The paper may well serve as an especially useful reference for rush-repairing and putting through the traffic lifelines in dangerous mountainous areas after a rare and highly intensive earthquake.
