Using the response spectrum analysis method to analyze the classification of natural vibration mode and distribution of natural vibration frequency of the steel arch access bridge in crude oil terminal. The natural vibration mode can be divided into five modes. Studied and concluded the linear correlation of frequency and half wave number of vibration mode.%利用MIDAS/Civil有限元分析软件反应谱分析法，对大型原油码头钢拱引桥进行自振模态与相应频率进行分析。得出引桥自振模态主要分五大类，对五类阵型的自振频率进行线性回归分析，得出了振型自振频率与振型半波数的对应关系。
