摘　　要：文中以西盐河桥为背景,按照规范要求,运用midas/civil有限元分析程序进行空间结构分析,由于斜交角的存在,斜交斜靠式系杆拱桥空间效应明显,受力较同条件正交桥梁复杂,不同侧主拱、副拱、系杆受力差别较大。荷载试验的布载方式应与结构实际受力情况一致,选择在钝角、锐角受力大的一侧进行试验分析。This paper uses MIDAS/civil finite element analysis program to carry out spatial structure analysis of Xiyanhe Bridge in accordance with the requirements of the code. Due to the existence of skew angle, the spatial effect of skew leaned tied arch bridge is obvious, and the stress is more complex than that of orthogonal bridge under the same conditions. The stress of main arch, auxiliary arch and tied beam on different sides is quite different. The distribution mode of loading test should be consistent with the actual stress of the structure, where the test analysis is carried out on the side with large stress at obtuse angle and acute angle.
