南水北调中线双洎河渡槽横杆受力分析

Shuangji River Aqueduct Rail Mechanical Analysis of South-to-North Water Diversion Project Middle Route

以南水北调中线工程中的双洎河渡槽为例,针对渡槽横杆的受力状况,采用三维有限元技术,建立了渡槽槽身的力学模型。对不同高宽比渡槽和不同槽内水深下的渡槽横杆的轴力进行了计算分析,得出了不同高宽比和槽内水深对渡槽横杆轴力的影响规律。

With the Shuangji River aqueduct of South-to-North Water Diversion Middle Route Project as research object,aiming at the mechanical analysis of aqueduct rail,the rectangular trough mechanical model was set up by 3D FEM technique.The axial force of aqueduct rail under different height-width ratio and different flux are calculated and analyzed.At last,the influence of the axial force of aqueduct rail under different height-width ratio and different flux was obtained.
