摘要
将可靠度理论应用于普定碾压混凝土拱坝，用ＪＣ法和三维随机有限元法，从坝体可靠度、坝体与坝基联合作用下整体稳定的系统可靠度及拱坝局部开裂可靠度三个方面进行综合论证，其结果符合三维模型试验的成果和该坝建成后的实际观测成果，该成果结论不仅指导了设计和施工，而且也可用来指导运行管理．
In this paper, reliability theory is used for Pu ding rolled concrete arch dam. JC method and 3 D SFEM are used to test dam reliability, partial crack reliability, and system reliability between the dam and the base. The resul is uniform with the 3 D model experiment and the inspected reality. The conclusions not only were applied to instruct designation and construction, but also can be applied to direct running management.
