摘　　要：地震震区斜坡崩塌落石、泥石流多发,常规钢筋混凝土结构明棚洞常作为防护此类斜坡地质灾害的重要工程措施。结合映秀—汶川—马尔康公路灾后重建工程,介绍了几种既保证结构安全,又解决了工程难题的新型结构,其中既有在传统结构基础上的优化,也有创新型的新颖结构,如半桥式明洞及棚洞等。In earthquake area,slope collapse,rockfall and debris flow occur frequently.The open shed tunnel with conventional reinforced concrete structure is often used as an important engineering measure to prevent such slope geological disasters.Combined with the post disaster reconstruction project of Yingxiu to Wenchuan to Markang highway,this paper introduces several new structures which not only ensure the structural safety,but also solve the engineering problems,there are not only the optimization based on the traditional structure,but also innovative new structures,such as half bridge open cut tunnel and shed tunnel.
