摘要
某大型水电站工程土石方开挖和填筑工程量大,做好土石方平衡规划对保证坝体填筑质量至关重要,因而在土石方平衡设计中,针对该工程特点及对填筑料的要求,本着"好料好用,差料差用、物尽其用"的原则,引入了"填筑对象-开挖料"分级的概念,将开挖料分为不同等级,用于不同的填筑对象,通过分级优先调配平衡,成功做到充分、合理地规划利用开挖料。
As the large amount of earthwork of a large-scale hydropower project,the earthwork balance plan is important to insuring the dam filling quality.According to the project characteristics and requirements on filling material,based on the principle of making best use of everything,we presented the concept of classifying the filling object and excavation material.The excavation materials were classified into different grades so as to be used for different filling objects accordingly.The balance was obtained through classification and allocation,so the excavation material was utilized rationally and fully.
