摘要:: 本文采用线弹性结构计算程序对漫湾水电站所用垫层不同的弹性模量和厚度进行了大量计算,并分析了弹性垫层对结构的影响规律。计算结果表明,垫层对结构的影响主要与其厚度弹模比有关。厚度弹模比大于一定数值后,对结构的影响基本上不再随之变化。这一结果已应用于漫湾水电站发电引水压力钢管的设计,对其它类似工程也有一定的参考价值。

Abstract:: This article uses a line elastic structure calculation program to calculate a large amount of elastic modulus and thickness of the cushion water station used by the Manwan Hydropower Station, and analyzes the influence of the elastic cushion on the structure. The calculation results show that the impact of the cushion on the structure is mainly related to its thickness model. After the thickness of the thickness is greater than a certain value, the impact on the structure is basically no longer changing. This result has been applied to the design of the water pipe of the water pipe of the power generation of the Manwan Hydropower Station, and it also has a certain reference value for other similar projects.
