摘要
三峡工程三期上游碾压混凝土围堰采用“围堰中段380m预埋药室(孔)倾倒爆破与两端深孔爆破相结合”的爆破拆除方案,本文对围堰倾倒可靠性进行了分析,详细介绍了围堰倾倒部分和两端炸碎部分的爆破参数及起爆网路的设计,并简要介绍了围堰爆破施工情况以及爆破效果。
The combination of inclined blasting of burying the barrel chambers at center-section 380 meters of the cofferdam and the deep-hole blasting at the two ends was employed in Three Gorges Project＇s Ⅲ-phase upstream roll compact concrete cofferdam demolition. The paper analyzed the reliability of the cofferdam and described in detail the design of the blasting parameters and ignition network. The paper also briefly introduced the blasting construction and the blasting effect.
