| 摘 要： | 本文采用空间杆系有限元方法，旨在对同跨度斜交渡槽与正交渡槽进行计算对比，使对斜交渡槽受力特性有一个较为清晰的认识，从计算结果对比来看，斜交渡槽的内力较为复杂，是典型的组合受力构件。

| Abstract: | This paper presents a spatial frame element analysis of large scale skew aqueduct bridge. Comparison is made between skew aqueduct bridges and straight aqueduct bridges. It is found that the internal force distribution of a skew aqueduct bridge is complicated compared with that of a straight aqueduct bridge. A skew aqueduct bridge is characterized by the internal forces of a composite structure. |
