摘要
Abstract
Two-graded concrete is normally used in the upstream and downstream for the seepage control of rolled dam,while three-graded concrete is used in the dam body itself.In the construction,,different kind of concrete mignt be mixed in placement in same block,affecting the construction quality.Placement of roller compacted concrete,normal concrete and mortar in the same block will affect construction progress.In the Kafue Gorge Lower Hydropower Station construction,the dam structure design was optimized based on the analysis and study of new concept,technology and processes of RCC design and construction,and quasi three-graded roller compacted concrete(max aggregate size of 63 mm)was used in the dam body,while in the upstream and downstream of the dam the roller compacted conrete was transformed into enrich-vibrated Rcc by adding sllury from the bottom and vibrating.关键词
