锦屏一级水电站大奔流沟料场运输方案研究

Study on transportation scheme for Dabenliugou quarry at Jinping Ⅰ Hydropower Station

锦屏一级电站大奔流沟料场开采运输面临着石料开采高峰强度大、料场内部明路修筑难度大等问题。介绍了两种运输方案:全汽车运输方案和溜井-平硐运输方案。从地形、经济及环境影响等方面出发,对两种方案进行探讨。分析比较表明,与全汽车运输方案相比,溜井-平硐运输方案运距短、土建工程量较小且运输强度易于保证,同时,能够适应山地陡峭地形,具有技术可靠、经济合理且节能环保的优点。最终选择溜井-平硐运输方案。

The excavation and transportation of Dabenliugou quarry at Jinping I Hydropower Station faces the problems of large peak excavation intensity and difficult construction of transportation path road inside the material quarry field.Two transportation solutions are introduced： all-cars transportation and chute-adit transportation.The two schemes are discussed from the aspects of terrain,economy and environment.It shows that comparing with all-cars transportation,the chute-adit transportation has the advantages of short distance,small civil construction quantity and guarantee of transportation intensity.Meanwhile,the latter solution is adapted to the steep topography,and it has the merits advantages of reliable technique,economy and energy conservation and environmental protection as well,so it was is selected as the transportation scheme.
