摘要
结合长江某航道水下炸礁工程,根据瑞典经验公式,初步确定该工程的炸药单耗值;之后通过现场正交爆破试验,确定了炸药单耗的合理取值为1.2 kg/m3,并运用ANSYS/LS—DYNA软件对正交试验的结果进行了数值模拟,模拟结果与现场试验较为吻合,验证了取值的可靠性与合理性。
Based on a project of underwater reef blasting engineering, the explosive specific charge was initially determined for this project, according to some empirical formula. And then through field orthogonal test, the reasonable value（ 1.2 kg/m3 ） was obtained ,which was compared with the result of numerical simulation by ANSYS/LS-- DYNA software. The result shows that the valve given by field orthogonal test was reasonable and reliable.
