加纳布维水电站土石坝心墙料碾压工艺参数的分析与选择加纳布维水电站土石坝心墙料碾压工艺参数的分析与选择 摘要：本文对国际水电工程加纳布维（EPC）水电站项目 1#副坝（土石坝）的心墙料碾压工艺试验的现场情况进行了介绍，对该土石坝所采纳的心墙料取土场的料源性质进行了必要的室内试验，通过分析介绍了粉砂、砾石和粘土混合料（以下称为土料）作为芯墙的碾压试验结果。本文着重介绍了该料场土料的碾压工艺试验过程和参数分析与选择。包括对碾压控制参数范围的选择、设备选型、场地布置、碾压顺序和试验成果分析等，展示了本工程心墙料碾压工艺试验的全过程，并通过分析得出碾压施工所实行的参数值。 关键词：土石坝；心墙料；参数；碾压；选择；布维 Abstract: This paper introduced on International Hydropower Project Garner Bouvet ( EPC ) Hydropower Station Project 1# auxiliary dam ( dam ) of the heart wall rolling process testing field, take the necessary the indoor test for the earth-rock dam with core wall material soil source material properties are, through the analysis of introduced silty sand, gravel and clay mixture ( hereinafter referred to as the soil material ) as the core wall of the compaction test results. The paper introduces the material field soil compaction technology of test process and parameter analysis and selection. Including the control of compaction parameters selection, equipment selection, site layout, rolling sequence and analysis of test result, showing the project core material and rolling process in the whole testing process, and through the analysis of the roller compaction construction taken by the parameter value.
