摘要
对三峡三期混凝土围堰拆除的爆破切口参数进行了计算 ,并对堰体的翻转运动进行了描述和分析 ,给出了堰体失稳、翻转的条件。此外 ,还提供了堰体翻转角 -时间(φ -t)和角速度 -时间 (ω -t) 的关系曲线。
In this paper,the blast cut parameters for demolition of the third stage cofferdam in the Three Gorges was calculated,the turnover movement of the cofferdam body described,and the conditions of destabilization and turnover of the cofferdam body were given In addition,the curves of turnover angle time(φ t)and angular velocity time(ω t)were provided
