【摘要】 对斜拉索的原长Ｓ０的导出结果作更正，并对斜拉索的水平距离ｘ、高差ｙ、索长Ｓ、原长Ｓ０作对比验证。证明斜拉索理论包含了悬链段理论，也包含了悬链线理论。斜拉索理论可以将这些理论统一。更多还原

【Abstract】 The derived results of the initial length S 0 of stayed cable are corrected, and the horizontal distance x , vertical distance y , cable length S and initial length S 0 of the stayed cable are contrastively verified. As a result, the theory of the stayed cable is proved to have already contained both theories of catenary segment and catenary which can be integrated by the former theory itself.更多还原
