摘要
通过分析三维表面模型在公路线形设计中的应用状况，指出了目前在应用上存在的困难及不足，由此进一步探讨了地表曲面与公路设计表面的三维表面模型建立方法以及模型拼合计算方法。
According to the analysis of the application situation of three dimensional surface model in highway alignment design, the shortcomings and difficulties in the current application are pointed out, and then the building methods for the three dimensional models of terrain and highway's design surface and the merging methods for the models are studied.
