本文首先对缆索护栏在国内外的研究和应用现状进行了综述,阐述了缆索护栏的结构组成,主要包括缆索、立柱、防阻块3个部分,对缆索护栏与其他护栏进行了对比分析,可以看出缆索护栏具有良好的经济效益、社会效益和环境效益,提出了缆索护栏的适用条件,最后分析了在设置缆索护栏时需考虑护栏的端部外展、变形量、布设位置、最小设置长度、初始拉力大小等因素,为缆索护栏在忻阜高速公路的推广应用打下了良好的理论基础。 In this paper, the current situation of research and application of cable guardrail both at home and abroad is reviewed. The structure of the cable guardrail is described, including three parts of cable, column and anti-blocking block. The comparative analysis of cable guardrail and other guardrail can be done. It is shown that the cable guardrail has good economic, social and environmental benefits, and the applicable conditions of the cable guardrail are proposed. Finally, it is necessary to consider the end abduction, deformation amount, laying position and minimum setting length of the guardrail when setting the cable guardrail , The initial pull size and other factors, laid a good theoretical foundation for the popularization and application of cable fence in Xin Fu Expressway.
