长河坝水电站土料场施工复查

Review on Soil Material Yard for the Construction of Changheba Hydropower Station

长河坝水电站大坝工程砾石土料分布范围广、土料性质均一性差。针对砾石土料的分布特点及其性状,在砾石土料施工复查期间进行了相关试验与分析,对土料质量和储量进行施工评价,并根据复查结果对下阶段的施工开采与试验提出指导性意见。

The gravelly soil material used for the dam construction of Changheba Hydropower Station project is widely distributed in different yards and the uniformity of soil property is poor. In view of the distribution and nature property of gravelly soil material, the reviews on soil material before project construction are conducted and relevant tests and analyses are carried out to evaluate the quality and reserves of soil material. According to review results, some guidance suggestions for following excavation and tests of soil material are then presented.
