杨东河水利枢纽大坝工程烧棒溪料场规划及开采

The Planning and Exploi Tation of Shaobangxi Stock-yard in Yangdonghe Multipurpose Dam Project

由于杨东河枢纽大坝工程地势陡峭,地质条件复杂,修路到达料场顶部进行料场开挖十分困难,因而杨东河水利枢纽大坝工程料场开挖是杨东河枢纽大坝工程施工的难点之一,其规划的好坏是杨东河水电站能否实现2010年度汛目标及按期投产的关键。根据公司专家意见及经现场参建各方的讨论,现有花郎坪料场依据现场的地形条件无法满足大坝上坝强度要求,因此,增选了烧棒溪料场,并对烧棒溪料场的开挖进行了方案比选,采用了有效的"之"字形道路方案,使设备通达料场顶部,为料场开采提供了有利的保障,为下一步填坝工作奠定了基础。

Because of the steep terrain and complex geological condition on Yangdonghe dam project,it is very difficult to conduct excavation from road to the top yard.Therefore,the excavation of the stock-yard is one of the difficulties of this project.The quality of planning is the key to achieve the 2010 flood prevention target and production schedule.According to the experts’advice of our company and discussion of the on-site parties participating in the construction,the existing Hualangping stock-yard,based on the topography of the site conditions,does not meet strength requirements of the dam.As this reason,we chose Shaobangxi stock-yard for extra usages and compared the programs of the excavation that carried out on the yard.We used an effective of the＂ zigzag＂road scheme,which makes the equipment accessible to the stock-yard at the top and feeds the market exploitation and laid the foundation for filling the dam for the next step.
