undermine pattern

The method of fuzzy theory is developed for optimization of six undermine patterns and relative parameters. The observation data are adopted for optimization,and the results show that the best undermine pattern is the wedge cut pattern.
利用模糊综合评价理论和现场实测数据，对隧道掘进中常用的6种掏槽方式及参数进行优化评价，评价结果表明，楔形掏槽的掏槽效果最佳，而在直眼掏槽中，三角柱掏槽、螺旋掏槽的掏槽效果较好。
