摘要针对兰州地铁首次盾构下穿黄河砂卵石地层，选用线弹性模型和扩展的线性Drucker-Prager塑性模型模拟卵石材料的本构关系，建立盾构刀具在砂卵石地层的破岩的数值计算模型，分析了刮刀切削速度为0.6m/s、0.8m/s、1.0m/s、1.2m/s；切削深度为6mm、9mm、12mm、15mm、18mm；切刀间距为12cm、16cm、20cm、24cm；刀具前角为10°、15°、20°、25°的情况下对砂卵石地层的破岩效果，得到：刮刀前角为20°时卵石的等效应力发生突增提供破岩应力，效果最好；另外分析了滚刀间距分别为8cm、12cm、16cm、20cm、25cm、30cm、36cm时的破岩效果，得到滚刀间距取12cm~16cm之间时破岩效果最佳。

Abstract：Aiming at the Yellowstone sandpebble formation under the first shield of Lanzhou Subway, this paper selected a linear elastic model and extended the linear DruckerPrager plasticity model to simulate the constitutive relationship of pebble material and established the numerical calculation model of shield rock breaking in rockpebble formation. The rock breaking effect on the Yellow River pebble stratum in several different situations was analyzed when Blade cutting speed was 0.6 m / s, 0.8 m / s, 1.0 m / s, 1.2 m / s; cutting depth was 6 mm, 9 mm, 12 mm, 15 mm, 18 mm; cutter spacing was 12 cm, 16 cm, 20 cm, 24 cm; The rake angle was 10 °, 15 °, 20 °, 25 °. According to the calculation results, when the blade rake angle is 20 °, the pebble equivalent stress suddenly increases to provide rock breaking stress, and the rock breaking effect is the best. In addition, the rock breaking effect was analyzed when the hob pitch is 8 cm, 12 cm, 16 cm, 20 cm, 25 cm, 30 cm and 36 cm respectively. The rock breaking effect was the best when the hob pitch was between 12 cm and 16 cm.
