摘要
快速拉格朗日法是一种新型的数值计算方法。本文介绍了快速拉格朗日法的基本原理和分析过程;并将这种方法应用于巷道锚杆支护的计算中,对锚杆支护前后围岩的变形进行了对比。结果表明锚杆在控制围岩垂直方向的变形有明显的作用。
Fast Lagrangian is a new type of numerical calculating method. This paper introduces the basic principle and analyzes procedure of Fast Lagrangian method; Then this method is used in the calculation of bolt support on coal goal, and deformation of goaf is compared before and after bolt support. The calculating result shows that the bolt support has obvious effect on controlling the displacement of rockstrata vertical orientation.
