中文摘要：

文章以巢湖市北部山区平顶山向斜为例，通过详细的野外调查，在进行精准的地质构造填图的基础上，对绘制正交剖面的过程进行了概括，并提出了计算机辅助编绘褶皱正交剖面的方法，其结果与手工绘制的正交剖面进行了比较，结果吻合。该法在保证精度的前提下提高了效率，为相关褶皱构造研究和实际应用提供了参考。

英文摘要：

In this paper, the Pingdingshan syncline in the northern mountainous area of Chaohu is taken as an example, and the drawing process of orthogonal profile is summarized based on the detailed field investigations and accurate mapping of geological structure. Then the computer-aided drawing method for fold orthogonal profile is proposed. The comparison between hand-drawn orthogonal profiles and computer-aided ones shows good agreement. The proposed method can improve the drawing efficiency on the premise of the required ac- curacy, and provides a reference for the related research and application of fold structure.
