arch aqueduct meaning in Chinese

拱式渡槽

On the mrp , the truss arch aqueduct is comprehensively researched in this paper , including its structural characteristic , structural calculation and reliability analysis
本文结合南水北调中线工程，对下承式空腹桁架拱排水渡槽的特点、结构计算以及结构的可靠性进行了较全面研究。
The comparative analysis is made firstly , which shows that the truss arch aqueduct can be built on the weak foundation and is also satisfied with the demand for large span length and the great discharge ability , so the type of aqueduct is a better for the project . then the finite element program ( super sap93 ) is applied to the structural analysis of the space structure
首先通过对常用渡槽结构型式的对比分析，阐明该渡槽是一种可在软弱地基上修建的、能满足大跨度、大流量要求、适用于南水北调中线工程的排水建筑物，然后运用有限元分析程序supersap93对桁架拱空间结构进行了受力分析。
