摘要
为验证大坝心墙接触黏土料的设计填筑标准,确定经济合理的碾压施工参数,选择适宜的碾压机械设备,以确保大坝碾压作业的施工质量,进行了心墙接触黏土料现场碾压试验。试验成果表明,选用的机械、机具及工艺满足现场碾压要求;该区域土体属中压缩性土,具中等偏下抗剪强度,极微透水性,土料适宜用于心墙接触黏土填筑。
The on-site rolling tests of contacting clay material for dam core wall construction in Luding Hydropower Station are conducted for verifying the designed filling criteria of contacting clay material, determining the economic rolling parameters and selecting appropriate rolling machineries and equipments. The results show that the selected rolling machineries and equipments and roiling technology can meet the requirements on on-site rolling construction, and the soil is middle compressible with lower-middle shear strength and very small permeable and is suitable for the filling of contacting clay.
