摘要
该文针对自锚式悬索桥主缆成桥线形的求解,介绍了抛物线法和分段悬链线法的原理和实际应用方法,并结合工程实例对两种方法进行了对比计算分析,同时,对影响抛物线法精度的主要参数进行了探讨。
Aiming at the seeking for the main cable bridge linearity of self-anchored suspension bridge,the article introduces the principles and the practical application methods of the parabola method and the subsection catenary method,contrasts,calculates and analyzes two methods according to the engineering cases,and at the same time,discusses the main parameters affecting the precision of parabola method.
