摘要
面板坝具有适应性好,抗震性强等优点,目前在新建和拟建的高坝中占有很大比例,随着砂砾石等材料的上坝,应用范围更为广泛。文章在研究面板砂砾石坝流变影响的基础上,进行防渗面板的有限元分析,总结出应力变形规律,所获成果可以为高面板砂砾石坝的流变效应研究提供必要的理论依据,对类似工程的设计运行具有一定的参考价值。
Plate dams have the advantages of good adaptability and strong vibration resistance and account for a large proportion in new and proposed dams presently, and will be applied widely with the sandy gravel used on the dam. According to the study on theological response of face sandy gravel dam, this paper conducts finite element analysis for impervious face slab and gets the law of stress deformation,and the results obtained will provide necessary theoretical accordance for the rheological response from high face slab sandy-gravel darn, meanwhile, having certain reference value for similar project design and operation.
