    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Super Sap93对桁架拱空间结构进行了受力分析。

This paper suggests two analytical methods of internal forces of arch aqueduct from the view point of the characteristics of its structural behaviour. Both methods confirm the interaction between main arches and rigidsuperstructures——2channels,spandrelpiers or columns and transverse brace-s, i.e.their deformations must be harmonic. The principle of this paper is compatible with each kind of arch aqueducts, such as double-curved arch aqueduct, ribbed arch aqueduct, trussed arch...

本文从拱渡槽的构造特点出发,提出拱渡槽内力的两种整体分析方法,充分考虑刚强的水槽、腹孔墩和横隔梁板等对主拱的协同变形和联合抗力.本文原理对双曲拱渡槽、肋拱渡槽和桁架拱渡槽等,都是适用的.

The flume at Cao River is an important building of centre-line projects for water sending from the south to the north.The paper researches and approaches in detail the construction schemes for underslung suspension of trussed arch,a main load-bearing structure of flume.\;

漕河渡槽是南水北调中线工程中的一座重要的输水建筑物。本文针对渡槽的主要承重结构预制桁架拱片的吊装施工方案进行了详细的研究和探讨。

By combination of the 3-D finite element method with the response surface method, a reliability analysis is made of the structure of the open-spandrel truss-arch type prestressed aqueduct, which has been widely used in the South-to-North Water Transfer Middle Route Project. The result shows that the reliability of the aqueduct structure meets the design requirement, and that the response surface method is an effective method for reliability analysis of the aqueduct structure of the open-spandrel...
