摘　　要： 对比研究了线弹性有限元法配筋和非线性有限元法配筋,指出前者在截面内力和配筋设计中使用的原理不匹配,使计算配筋量偏大,而后者适用面广,能反映结构实际承载效应,使配筋设计经济合理。结合某工程调压井的结构分析,对比了2种有限元配筋法的配筋设计,说明非线性有限元配筋法是值得推广的。 Reinforcement arrangement methods of concrete lining using finite element methods in surge-chambers are studied, including linear method and nonlinear method. In the former, the theories to acquire internal force and reinforcement arrangement are unmatched, which results in overloading quantity of bars. Using the latter, load-bearing can be show in its law, and the reinforcement arrangement is rational and economical. A contrastive analysis is done on the surge chamber of a hydropower station. The procedures and results of the two methods are illustrated, and it is concluded that the nonlinear method is effective in analysis of surge-chamber.
