摘要
南水北调北京密云水库调蓄工程穿密关路入水隧道初衬采用浅埋暗挖法施工,二衬浇筑C20自密实混凝土,设计并试验了C20P12自密实混凝土,成功应用在密云段蓄水工程中,得到流动性优良、钢筋通过性能佳、强度和耐久性满足工程要求的混凝土。
South North Water Diversion Beijing Miyun reservoir regulation and storage engineering through sealed road entering the water tunnel is lined with shallow excavation method, the secondary lining pouring C20 self-compacting concrete. This paper designs and tests the C20P12 self-compacting concrete, which is successfully used in the Miyun reservoir water storage project.The concrete structure has good fluidity, good strength, strength and durability.
