某水库上坝道路方案比选分析

Comparison and Analysis of Road Scheme for a Reservoir Dam

上坝道路不仅是水库枢纽工程建设期、运行期关键的组成部分,更是连接大坝与外界的通道。基于某水库库区工程地质条件、线路布置、施工工期、造价、运行管理等方面的综合考虑,文章提出明挖道路与坝后之字路两个上坝道路方案,经过比选分析,选择更优的坝后之字路方案作为上坝道路,以期为类似工程的设计提供思路。

Dam road is not only a key component of the construction and operation period of the reservoir project,but also a passage connecting the dam with the outside traffic.Based on the comprehensive consideration of engineering geological conditions,route layout,construction period,cost and operation management in a reservoir area,the paper puts forward two schemes for roads to mobilization,open excavation road and zigzag road behind dam.After comparison and analysis,we choose the better scheme of the zigzag road behind the dam as the dam road,in order to provide ideas for the design of similar projects.
