摘要
以龙潭高混凝土大坝为例,采用基于扩展有限元法的ABAQUS程序,对裂缝扩展研究常用的静力和动力条件下的龙潭大坝进行分析,提出了混凝土重力坝裂缝扩展的数值预测方法,分析了龙潭大坝易产生裂缝的位置。结果表明,在地震活动中龙潭大坝相当不安全,研究结果对大坝系统的设计和运行具有指导意义。
This paper took the Longtan high concrete dam project as an example and used expanded finite element-based ABAQUS program to analyze crack development on Longtan dam under frequent static and dynamic conditions.It proposed numerical estimation method for concrete gravity dam and analyzed frequent cracking positions on Longtan dam.It was found that Longtan dam is very dangerous in earthquake and the research findings has guiding significance for dam system design and operation.
