摘　　要：本文首先对目前应用较广的膜结构裁剪方法,即裁剪线生成与图形展开的方法进行了比较研究,并在此基础上提出了一种新的裁剪方法——二次测地线法.通过对有理论解算例的分析及对不同形式的膜结构进行裁剪,验证了本方法的正确性、可靠性及广泛适用性.A few generation methods of cutting patterns including cutting line generation methods and cloths flattening methods are studied, and the advantages and disadvantages of each method are clarified. Furthermore, a new cutting pattern generation method Secondary Geodesic Line Method is put forward. The correctness and reliability of the proposed method are verified by examples with classical solutions. Cutting patterns of a few cablefabric structures satisfying various requirements show the favorable applicability of the proposed method.
