摘要
本文按能量原理推导了平面圆形曲梁的单元刚度矩阵,提出了带螺栓接头管片式衬砌的计算方法,并对国内首次采用的拼装式管片衬砌输水隧洞的受力特性进行了分析。
Based on energy principles,the element stiffness matrix,equivalentjoint load and the calculation method for segmented lining with boltconnection were derived,and were used for analysis the stress characte-ristics of segmented lining structures.
