摘　　要：以一座四跨(72m+120m+120m+72m)预应力混凝土部分斜拉桥为工程背景,利用空间有限元来模拟真实的桥梁,进行空间受力分析,得出部分斜拉桥横梁的内力分布特点,并用简化算法与其比较,得到比较接近实际的简化算法。As the engineering background with the part of cable stayed bridge of prestressed concrete with four spans of 72m, 120m, 120m and 72m, the paper emulates the real bridge by space finite element for analysis of space load bearing. In the result there have been gained the features for internal force distribution of transbeam of part of cable stayed bridge, and calculated them by shortcut method approaching the practice.
