水口水电站枢纽坝下拆除围堰施工技术及控制措施

Construction Technology and Control Measures of Removing Cofferdamunder the Hub Dam of Shuikou Hydropower Station

基于理论与实践相结合视角,以福建闽江水位治理与通航改善工程围堰拆除为案例,梳理一项适用性广、实操性易、指导性强的围堰拆除施工技术,重点分析围堰拆除施工总体布置、拆除工艺、围堰边坡稳定性、爆破拆除参数等,从施工技术、质量及安全三方面相应制定围堰拆除施工的控制措施,供类似水利水电工程围堰拆除施工指导。

Based on the combination of theory and practice,taking the demolition of the embankment for the flood control and navigation improvement project of the Minjiang River in Fujian as a case study,a systematic review of a practical and easy-to-operate embankment demolition construction technology is carried out.The paper also focuses on the embankment demolition construction technology,including the overall layout,demolition process,slope stability of the embankment,and blasting demolition parameters.Control measures are formulated from the perspectives of construction technology,quality and safety to provide practical guidance for similar hydropower and water conservancy engineering embankment demolition construction technology.
