对雁盐黄河大桥成桥状态进行了结构分析，并采用 SAP 有限元分析程序，利用虚功原理方法计算了主拱肋及副拱肋控制截面的内力影响面，绘制了主拱控制截面的内力包络图，同时在桥梁横向计算中考虑横向预应力及人群活载的效应，对主桥控制截面进行了成桥状态各种分析和验算，以供参考。
對雁鹽黃河大橋成橋狀態進行瞭結構分析，併採用 SAP 有限元分析程序，利用虛功原理方法計算瞭主拱肋及副拱肋控製截麵的內力影響麵，繪製瞭主拱控製截麵的內力包絡圖，同時在橋樑橫嚮計算中攷慮橫嚮預應力及人群活載的效應，對主橋控製截麵進行瞭成橋狀態各種分析和驗算，以供參攷。

This thesis is to analyse the frame which is directed at the Yanyan Huanghe bridge. SAP is used to calculate the internal force influ-ence field of main and sub arch ribs’critical section by way of utilizing finite element analysis program and principle of virtual work. The inner force envelope was drew. In the calculation of cross section,the effect of cross prestress and pedestrian load were considered,and various sorts of analysis and checking of existing state were done,for reference.
