白河水电站的混凝土骨料料源有3类，分别为工程开挖料、天然砂砾石料及人工开采块石料。为降低工程造价、减少工程弃渣及保护周边环境，料源优先选择满足要求的工程开挖料，不足部分从规划的天然砂砾石料场中择优选取。工程采用分期导流，工期受汉江洪水影响较大，为保证混凝土浇筑进度，必须做好料场的开采、备料计划，制定安全、可行的开采方案。

In the construction of Baihe Hydropower Station, three sources of the concrete aggregate are available, i.e. the excavation materials, natural sand and gravel, and artificial exploited stones.In order to cut the construction cost, reduce the construction waste and protect the surrounding environment, it is recommended to take excavation materials that meet the construction requirements as the first choice of aggregate source.And insufficient materials should be a-dopted from the natural sand and gravel.On the other hand, flood of the Hanjiang River has a serious influence on the construction as a staged diversion scheme is adopted.Thus, a safe and feasible exploitation plan for the aggregate mate-rials should be made to ensure the construction schedule.
