摘　　要：介绍了修正惯用法管片环弯曲刚度有效率和弯矩提高率的定义,论述了用梁-弹簧模型确定弯曲刚度有效率和弯矩提高率的方法,研究了接头刚度对弯曲刚度有效率和弯矩提高率的影响,提出了管片环弯曲刚度有效率和弯矩提高率的拟合公式,对盾构管片的设计具有一定的指导作用。It is introduced the definition of effective bending rigidity ratios and moment increasing rates, and it also discusses the method which can be used to determine the effective bending rigidity ratios and moment increasing rates with beam-spring modal. The effect of the joint stiffness on the effective bending rigidity ratios and moment increasing rates is researched, thus presenting the fitting formula of the effective bending rigidity ratios and moment increasing ratios, which has guidance to designing shield segment.
