三峡工程纵向围堰上游端部拆除爆破震动安全监控

Monitoring and control of vibration of dam during blasting demolition of upstream longitudinal concrete cofferdam at Three Gorges Project

在三峡工程混凝土纵向围堰上游端部拆除前后的爆破试验和施工爆破过程中,对混凝土大坝及其周围建(构)筑物的关键部位进行了振动测试。爆破效果调查表明,此次围堰拆除爆破是成功的。

During the blasting test and construction blasting of the upstream longitudinal concrete cofferdam of Three Gorges Project, vibration monitoring was conducted at the key locations of concrete dam and its surrounding structures. The post-blasting investigation of the effect of blasting indicated that the demolition blasting of the cofferdam was successful.
