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.
利用模糊綜合評(píng)價(jià)理論和現(xiàn)場(chǎng)實(shí)測(cè)數(shù)據(jù)，對(duì)隧道掘進(jìn)中常用的6種掏槽方式及參數(shù)進(jìn)行優(yōu)化評(píng)價(jià)，評(píng)價(jià)結(jié)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較好。
