| 摘 要： | 大型水电站围堰拆除爆破要考虑爆破振动波、水击波、涌浪及动水压力、个别飞石等效应对邻近建筑物的影响,并针对不同类型的建筑物物理特性,制定恰当的爆破安全控制标准,并采取相应的措施,使爆破有害效应控制在允许范围以内。本文以小湾水电站导流洞围堰爆破拆除为例,总结分析了爆破拆除过程中的问题及相应的解决方法。

| Abstract: | In blasting demolition of cofferdam and rock ridge of large hydropower station,the effects of blasting vibration,water blast wave,surging wave and unexpected slungshot etc to surrounding construction must be considered.And it is also necessary to establish appropriate blast safety control criterion for the physical characteristic of different style building and to adopt corresponding measures for making the blasting destructive impact controlled under safety scope.The present paper summarizes and analyzes t... |
