盾构刀盘在掘进过程中受到周围环境的影响工作状态随时改变,文章通过将盾构刀盘掘进过程简化为刀盘刀具掘土作用,采用数值方法对刀盘掘进过程进行了全物理过程仿真,分析了地质参数、施工参数以及结构参数等影响因素对处于稳定工作状态的盾构刀盘切削力及扭矩等动态掘进载荷分布的影响。 Shield cutterhead in the process of boring by the impact of the surrounding environment from time to time to change the status of the article through the shield cutterhead boring process simplified to cutter cutter earthworking effect, the numerical method of the cutterhead during the whole physical process simulation The influences of geological parameters, construction parameters and structural parameters on the dynamics of cutting load, such as cutting force and torque of shield cutterhead in stable working condition were analyzed.
