第四章第六节机械要素一、总推力决定盾构总推力的主要因素有下列四方面: ①盾构外用(盾壳)与土体的摩擦阻力,或粘着阻力; ②正面阻力; ③管片与盾壳的摩擦阻力; ④刀头头部的切入阻力。
Chapter IV Section 6 Mechanical Factors I. Total Thrust The main factors that determine the total thrust of the shield are the following four aspects: (1) the frictional resistance or adhesion resistance of the external shield (shield shell) to the soil; (2) the positive resistance; Film and shield shell friction resistance; ④ cutting head cutting resistance.
