爆炸离心模型试验研究进展与展望

Development and prospect for centrifugal blasting modeling

由于能量比尺和原型应力模拟的优势,采用离心机进行爆炸试验具有无可比拟的优越性。在简要介绍土工离心机的发展历程的基础上,对爆炸离心模型试验较关注的问题——模型箱、爆炸源、离心模型比尺、数据采集、科氏加速度等方面的研究进行了归纳,对已有的研究领域进行总结并对以后的发展提出了自己的看法——模型箱设计需考虑防风措施、能量比尺仍需采取更精确方法验证、需制作稳定性好及质量有保证的微型炸药源等。

Because of the superiority in energy scale and modeling prototype stress,soil geotechnical centrifuge have unique advantage in the blasting modeling.Based on the progress for soil geotechnical centrifuge,some aspects in blasting centrifuge modeling such as modeling box,explosion source,centrifuge modeling scale,data collecting and Coriolis effects are concluded,also the known research domain.The development tendency in blasting centrifuge modeling is presented,for example,the measure such as anti-wind should be considered in designing model box,a more accurate method should be adopted to verify the energy scale;micro-explosive source should be more stable and in good quality.
