以混凝土斜拉桥A字型桥塔为例，基于A PDL语言研究桥塔有限元参数化建模方法。首先研究相关特征提取算法，提取斜拉桥点云模型特征点；然后使用ANSYS软件，建立桥塔有限元参数化模型；最后分析模型结构，建立相关数学约束关系。该方法实现了对有限元模型的参数化控制，缩短了有限元模型建立的周期。

Taking a tower of concrete cable-stayed bridge with A-line shape as an example ,we used APDL to research the finite element parametric modeling method of the bridge tower based on ANSYS .At first ,the related feature extraction algorithm was studied and feature points of the point cloud model were exacted .Then the finite element parametric model for the tower was constructed using ANSYS ,finally the structure of the model was analyzed and the related mathe-matical constraint relations were established .Thus the coercion of parametic for finite element model was realized ,and the cycle time of finite element model of construction was cut down .
