承载索式跨越装置中承载索的施工设计及计算研究

The Construction Design and Calculating Study of Carrying Rope of Over-crossing Device

承载索式跨越装置由支撑装置、 承载索和封网装置组成, 是线路跨越施工中常用的跨越施工装置.承载索式跨越装置施工设计的核心是承载索的张力计算和规格选择.本文针对承载索的正常工况和事故工况下的受力及相互关系进行详细分析, 给出了施工设计流程、 计算方法及优化方法, 为承载索跨越施工提供理论依据和安全保障.

The over-crossing device by carrying rope consists of supporting device,carrying rope and closed net, is commonly used in line crossing construction across the construction unit. The design of the overcrossing device by carrying rope is he core of tension calculation and choice of specification. In this paper under normal condition and accident conditions in a force and the mutual relationship of detailed analysis,construction design process was given, calculation method and optimization method, as to provide theoretical basis for over-crossing device by carrying rope construction and security.
