摘　　要：长江三峡工程三期上游碾压混凝土围堰中段380 m采用预埋药室(孔)向上游倾倒爆破法予以拆除,围堰倾倒时产生的涌浪是否会对周围建筑物和环境造成危害,一直是人们关注的问题,通过1∶100的围堰倾倒模型试验,测得了围堰倾倒时的涌浪特性、传播规律,并预测了实际围堰爆破时将产生的涌浪高度,对围堰爆破的安全防护设计具有重要的指导意义。实际围堰爆破时的涌浪观测资料也验证了模型试验成果的正确性。The upstream roller compactions concrete cofferdam demolition the third issue in Three Gorges of Yangtze River hydro-junction of used ＂the cofferdam center-sectlon 380 meters bury the barrel chambers and holes inclined blasting combination with the beginnings and ends using deep-hole blasting＂. Whether the swell produced by the coffer dam falls can causes the harm to the periphery building and the environment, is always the problem people concerned. Through the model experiment of 1：100 coffer dam, the swell characteristic and the dissemination rule when the coffer dam falls, are obtained, and produced altitude the swell in actual coffer dam demolition is forecast. The swell＇s data observed in the actual coffer dam demolition blasting have also confirmed the accuracy of model experiment achievement.
