王堤口橡胶布双曲扁壳新型闸门的面板受力分析

FACEPLATE MECHANICAL ANALYSIS OF A NEW STYLE DOUBLE ARCH FLAT SHELL SLUICE MADE OF RUBBER CANVAS IN WANGTIKOU

薄壳空间结构具有很多优点,我国在水工闸门中使用双曲扁壳结构的历史已有37年,但尚未见到采用橡胶布面板的。我们结合工程实际,采用薄膜理论并采取相应的结构和构造措施,进行了胶布双曲扁壳新型闸门的具体分析与设计。工程应用中不但能消除面板的角点影响,而且保证了面板的无弯矩状态。

The thin shelled space structure has many advantages and has been for many than 37 years in the water power engineering in China. However the rubber canvas face plate has not been used befone. According to this film theory and its application in enginearing and considering its structune and manufacture characters,a new style double area flat shell sluice made of rubher canvas was designed and analysize. Not only the corner affection has been eliminated,but also the bending moment was not appeared.
