In order to qualitatively and quantitatively grasp the influence of the installation elevation of horizontal water stops at transverse joints on the structural stress of the bulb tubular power house, taking a certain engineering project as an example, a three-dimensional finite element model of the powerhouse was established to analyze the stress of the structure on the condition of the horizontal water stops changing within a certain range. The results show that the installation height of horizontal waterstops has a significant impact on the stress of structure, and an appropriate installation height of horizontal waterstops can improve stress of structure. Taking into account various factors, the optimal horizontal water stop installation height is 70% of the installable height, which can provide a reference for the design of the transverse joint water stop of the bulb tubular power house.

为定性定量掌握横缝水平止水的安装高程对灯泡贯流式机组厂房流道各部位结构应力的影响,以某工程项目的厂房流道结构为例,建立了三维有限元整体模型,研究了机组间横缝水平止水在一定安装高度范围内变动时厂房流道各部位结构的应力变化规律。结果表明,水平止水的安装高度对结构应力影响显著,合适的水平止水安装高度可改善结构受力,综合考虑各因素,最优的水平止水安装高程为可安装区间高度的70%,为灯泡贯流式水轮机组厂房流道横缝止水结构设计提供参考。

为定性定量掌握横缝水平止水的安装高程对灯泡贯流式机组厂房流道各部位结构应力的影响,以某工程项目的厂房流道结构为例,建立了三维有限元整体模型,研究了机组间横缝水平止水在一定安装高度范围内变动时厂房流道各部位结构的应力变化规律。结果表明,水平止水的安装高度对结构应力影响显著,合适的水平止水安装高度可改善结构受力,综合考虑各因素,最优的水平止水安装高程为可安装区间高度的70%,为灯泡贯流式水轮机组厂房流道横缝止水结构设计提供参考。

In order to qualitatively and quantitatively grasp the influence of the installation elevation of horizontal water stops at transverse joints on the structural stress of the bulb tubular power house, taking a certain engineering project as an example, a three-dimensional finite element model of the powerhouse was established to analyze the stress of the structure on the condition of the horizontal water stops changing within a certain range. The results show that the installation height of horizontal waterstops has a significant impact on the stress of structure, and an appropriate installation height of horizontal waterstops can improve stress of structure. Taking into account various factors, the optimal horizontal water stop installation height is 70% of the installable height, which can provide a reference for the design of the transverse joint water stop of the bulb tubular power house.
