摘要:
利用DDA方法对船坞围堰的拆除爆破进行数值模拟,分析倾斜孔低水位、倾斜孔高水位、垂直孔和倾斜孔结合低水位以及垂直孔和倾斜孔结合高水位4种不同方案下的爆破特性和规律。研究结果表明:在某公司1#、2#船坞围堰的拆除爆破过程中,水位高低对倾斜孔装药影响不大,对垂直孔和倾斜孔结合装药有明显影响;垂直孔和倾斜孔结合装药高水位工况下形成的边坡较缓,低水位工况下形成的爆堆较低,容易产生水突然涌入坞门的现象;综合分析,选择倾斜孔装药爆破会得到更好的爆破效果。
Abstract:
DDA method was used to simulate the demolition blasting of dock cofferdam. Blasting characteristics and rules in 4 different states, including inclined holes low water level, inclined holes high water level, vertical holes combined with inclined holes low water level and vertical holes combined with inclined holes high water level, were analyzed. The results show that in the demolition blasting process of 1# and 2# dock cofferdam of a company, the water level has little effect on the charge of slant holes, but has significant effect on the combination of vertical holes and inclined holes. Vertical holes combined with inclined holes form a gentler slope in high water level, and a lower rock pile in low water level. Both of them may result water pour into dock instantly. Under the comprehensive analysis, it shows that the charge of inclined holes will get better blasting results.
