【摘要】：面板堆石坝因抗震稳定性以及变形适应性较好而在我国水利工程中得到了广泛的应用，在强震区的深覆盖层上已经成为首选的建坝坝型。本文参照河口村面板堆石坝的一些参数，建立了面板堆石坝的有限元模型，分析了不同覆盖层厚度下面板堆石坝坝体以及面板的静力动力特性，并总结了覆盖层厚度对面板坝坝体以及面板静、动力特性的影响规律，为以后深覆盖层上面板堆石坝的设计以及施工提供了一定的理论基础。本文的工作主要包含如下几个方面：（1）选择适合深覆盖层上面板堆石坝的静力、动力本构模型，编制有限元子程序，实现有限元计算；（2）以河口村面板堆石坝工程为例，建立不同覆盖层厚度的面板坝有限元模型，通过静力分析，，给出面板和坝体在不同覆盖层厚度下的静力特性及变化规律；（3）以静力计算为基础，对大坝进行动力计算，分别给出面板和坝体在不同覆盖层厚度下的动力特性及变化规律。
[Abstract]:Face rockfill dam has been widely used in water conservancy projects in China because of its good seismic stability and deformation adaptability. It has become the preferred dam type in the deep overburden of strong earthquake area. According to some parameters of Hecoucun concrete face rockfill dam, the finite element model of face slab rockfill dam is established in this paper, and the static and dynamic characteristics of face slab rockfill dam body and face slab under different overburden thickness are analyzed. The influence of the overburden thickness on the static and dynamic characteristics of the slab dam is summarized, which provides a theoretical basis for the design and construction of the rockfill dam on the deep overburden. The work of this paper mainly includes the following aspects: (1) choosing the static and dynamic constitutive model of the concrete face rockfill dam on the deep overburden layer and compiling the finite element subroutine to realize the finite element calculation; (2) taking Hekou Village concrete face rockfill dam as an example, the finite element model of face slab dam with different overburden thickness is established. Through static analysis, the static characteristics and variation law of face slab and dam body under different overburden thickness are given. (3) on the basis of static calculation, the dynamic characteristics and variation laws of face slab and dam body under different overburden thickness are given.
