摘要

研究目的:推导盾构隧道管片接头抗弯刚度计算公式,研究不同影响因素作用下接头抗弯刚度的变化规律。
研究结论:管片接头的接触面有效高度和接触面偏心距对管片接头抗弯刚度的影响显著,因此管片结构设计中,通过改变管片接头构造尺寸来调整管片接头刚度是一种有效的手段。

Abstract

Research purposes: The purposes are to deduce the calculation formula for flexural rigidity of duct piece joint of shield tunnel and do the research on the change regularity of the different factors influencing the flexural rigidity of duct piece joint.
Research conclusions: The effective highness and eccentricity of the contacting face of duct piece joint have big influences on flexural rigidity of duct piece joint, so it is an effective way to change the structure size for adjusting flexural rigidity of duct piece joint in design of duct piece structure.
