摘　　要：盾构刀盘是盾构机掘进过程中的重要部件,刀具的配合及布置对盾构的掘进效率影响大。以北京地铁12号线某标段盾构工程为依托,通过数值模拟研究切削速度、相对切深和相对刀距对切削效果的影响。结果表明,切削速度与耕松效率呈正相关;相对切深显著影响切削力和耕松效率,相对切深为20~30 mm的综合效果较佳;相对刀距对耕松效率有显著影响,在模拟工况下相对刀距取125~150 mm时适应性与经济性较好。结合模拟结果对盾构刀盘提出系列适应性优化措施,施工效果良好,节约了工期,提高了工程效益。The shield cutter head is an important part of the shield tunneling process,and the coordination and arrangement of the cutters greatly affect the shield tunneling efficiency.Based on the shield tunneling project of a section of Beijing Metro Line 12,the influence of cutting speed,relative depth of cutter and relative blade distance on the cutting effect was studied through numerical simulation.The cutting speed is positively correlated with the ploughing efficiency;the relative depth of cutter significantly affects the cutting force and the ploughing efficiency,and the relative depth of cutter of 20~30 mm has a better overall effect;the relative blade distance has a significant impact on the ploughing efficiency.The adaptability and economy are better when the relative tool distance is 125~150 mm under simulated conditions.Combined with the simulation results,a series of adaptive optimization measures are proposed for the shield cutter head.The construction process shows that the effect is good,the construction period is saved,and the project benefit is improved.
