基本解釋[地球科學]掏槽專業(yè)釋義地球科學掏槽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.利用模糊綜合評價理論和現(xiàn)場實測數(shù)據，對隧道掘進中常用的6種掏槽方式及參數(shù)進行優(yōu)化評價，評價結果表明，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。
