摘要
针对道路水毁冲失段公路交通应急通行的迫切需要,以花横公路宝华段道路冲失段工程为依托,提出了栈道型应急修复结构新方法。在介绍栈道型应急修复结构组成的基础上,采用材料力学和极限平衡理论,提出了该结构的稳定性计算方法。计算结果表明:栈道型应急修复结构安全可靠,简单实用,能够满足应急通行快速修复交通的需求。
The new method of plank road emergency repair structure is put forward against the urgent demand of emergency traffic of the water damaged washout section of the highway based on the project of washout section of Hualin-Hengyanping Highway Baohua Section. The calculation method for the stability of the structure is proposed based on the introduction of composition of plank road emergency repair structure with mechanics of materials and ultimate balance theory. The results show that the plank road emergency repair structure is safe, reliable, simple and practical which could meet the demand of fast repair of emergency traffic.
