混凝土控制拆除是水电工程续建、扩建、再建项目施工中的重点与难点问题之一。通过系统分析混 凝土控制拆除的技术要求，总结了混凝土控制拆除施工常用方法的优点、适用条件和实施要点，建立了混凝 土控制拆除施工方法选择标准体系。同时，将该体系应用于南水北调中线丹江口大坝加高工程的施工实践 中，各项控制拆除工作实施效果良好。建立的混凝土控制拆除施工方法选择标准体系和丹江口大坝加高工 程中的典型实例可供类似工程借鉴参考。

Controlled demolition of concrete is one of the important and difficult problems in construction of reconstruction projects and expansion projects of hydropower projects . Based on systematic analysis of technologic requirements of controlled demolition of concrete , advantages , application conditions and implementation key points are summarized . That' s the selection criterion system of construction methods for controlled demolition of concrete . And the system is applied in Danjiangkou Dam heighting project of median- line of South- to- North Water Transfer Project . The final implementation effect is satisfying . The selection criterion system of construction methods for controlled demolition of concrete and representative successful implementation cases in Danjiangkou Dam heighting project will be helpful for similar projects in the future.
