张吉怀官田隧道施工中炮泥堵塞的应用与研究

Application and Research of Mud Blockage in Zhangjihuai Guantian Tunnel Construction

以张吉怀铁路官田隧道项目施工为例,对炮泥堵塞及最优长度进行研究,得到炮泥在爆破过程中的运动规律,对下段炮泥爆炸运动四个阶段详细的分析,并结合牛顿第二定律,提出了炮泥运动的物理模型,列出最优炮泥堵塞长度计算公式,计算出炮泥最优堵塞长度,为类似工程提供借鉴。

Taking the construction of the Guantian Tunnel project of Zhangjihuai Railway as an example,the artillery mud blockage and the optimal length are researched,and the motion law of the artillery mud during the blasting process is obtained.The second law proposes a physical model of the artillery mud movement,formulates the calculation formula of the optimal artillery mud plug length,and calculates the optimal artillery mud plug length,which provides a reference for similar projects.
