悬臂大模板在龙华口水电站混凝土大坝施工中的应用

悬臂大模板施工技术因具有施工速度快、施工接缝少、工程质量高、施工安全、劳动强度低、无脚手架消耗、总体投资少等优点,已在很多工程中得到应用.文中结合山西省孟县龙华口水电站工程碾压混凝土重力坝工程实际情况,从施工技术难点分析、工艺研究和改进、应用效果等方面对该技术做了较为系统的介绍.

Application of large Cantilever Form in Constructing Concrete Gravity Dam of Longhuakou Hydroelectric Power Station

Because the construction technique of large cantilever form has many advantages such as fast construction speed, few construction joints, high construction quality, security in construction process, lower labour strength, not having consumption of scaffold and lower total construction cost, so this technique has been adopted in many projects. In combination with the actual situation in constructing the roller compacted concrete gravity dam of Longhuakou Hydroelectric Power Station, Shanxi Province, the paper introduces systematically this technique from following aspects： analysis of construction difficulty, technique study ＆ improvement and application effect.
