摘要
在复合盾构掘进过程中,刀盘扭矩是一个重要的施工参数,它的大小影响盾构机掘进过程中的地质适应性。从盾构机的工作原理分析了复合盾构刀盘扭矩的构成,从数学和力学的角度推导出了各扭矩的计算方法,并从复合盾构刀盘的扭矩影响因素分析,得到了在盾构和地质一定的条件下,可通过土体改良改变盾构刀盘扭矩使其实现地质适应性,通过实例验证了扭矩的计算方法及通过土体改良实现复合盾构适应地质条件的合理性。
The cutter torque is an important working parameter in the tunneling, which affects the geological adaptability. The composition of shield cutter torque was analyzed based on the working principle of EPB. And every torque calculation methods were deduced from mathematics and mechanics. Based on cutter torque influencing factors, the operator can realize geological adaptability by soil improvement in the existing shield and geological conditions. At last the rationality of torque calculation methods and geological adaptability measures were verified by examples.
