摘要
水丰水电站位于中朝界河鸭绿江上,其主坝工作桥拆除工程量大、实施难度高。通过周密的控制爆破方案设计和计算分析,将其成功拆除;且爆破振动速度、动水压力和涌浪等监测指标以及大坝裂缝、渗漏量等宏观现象调查均处于安全范围以内。
Shuifeng hydropower station locates in the Yalu River between China and North Korea. The service bridge on the main dam would be aismantled, which was large work quantity and high difficulty. It was successfully demolished by means of careful controlled blasting scheme design and calculation analysis, and the monitoring indexes such as the blasting vibration velocity, the hydrodynamic pressure, and the swell were all within the safety range and so were the macroscopic phenomena such as the dam crack and the seepage discharge.
