摘要
狮子坪水电站大坝防渗墙由于施工原因需拆除顶部1 m^2 m,通过制定合理的爆破设计参数及孔网布置,采取科学的拆除程序及施工方法,最大限度地减小了爆破对设计高程以下防渗墙的影响。事后进行的宏观检查和声波测试分析表明,此次拆除爆破设计是成功的。
The process of demolishing the top 1-2 meters of anti-seepage wall in Shiziping Hydropower Station is introduced. The effect of blasting imposing on anti-seepage wall beneath the designed elevation is minimized through rational blasting parameters and disposing hole-meshwork, as well as scientific removal procedure and construction methods. The macroscopical examination and ultrasonic test illustrate that the demolition design is feasible.
