摘要
船坞围堰爆破拆除采用围堰内不充水爆破方案时,必须控制过流。本文针对围堰爆后易发生过流的特点,从爆破参数设计、钻孔形式、起爆技术及爆破时潮位选择等方面对过流控制措施进行论述。此控制措施在工程实践中应用表明是有效的,可供类似的爆破工程参考。
Overflow must be controlled if there isn＇t water in the dock, when the dock cofferdam is removed by blasting. Control measures about overflow had been discussed in detail in view of blasting parameter design, form of drill hole, initiation technique, and selection of sea level during blasting. The control measures were proved to be valid by the engineering practice, and had reference value to similar projects in design and construction of blasting.
