装配式圆形衬砌接头刚度计算方法

Calculation Method for the Rigidity of Assembly Circular Lining Joints

该文考虑衬砌接头对内力和位移的影响,就衬砌的接头刚度计算进行了研究和探讨。作者从研究开裂钢筋混凝土的截面刚度出发,导出了接头的截面刚度,并进一步阐述了拼装结构在长效轴力作用下对接头的刚度影响。

Considering the effect of lining joints on inner force and displacement, study has been made on rigidity calculation of lining joints. Based on the study on sectional rigidity of cracking reinforcement concrete, the sectional rigidity of joints has been calculated and the effect of assembly structure on rigidity of joints under long-effect axial force has been described as well.
