缆索护栏在公路安全生命防护工程中的应用

Application of Cable Rope Guardrail in Highway Safety and Life Protective Engineering

阐述缆索护栏的结构组成(主要包括缆索、立柱、防阻块3个部分)。通过对缆索护栏与其他护栏进行对比分析可知,缆索护栏具有良好的经济效益、社会效益和环境效益。提出缆索护栏的适用条件,最后分析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,为缆索护栏在公路安全生命防护工程的推广应用提出个人的观点供参考。

The article sets forth the structural composition of cable rope guardrail(mainly including three parts of cable rope, stand column and stop block). The comparison and analysis of cable rope guardrail and the other guardrails show that the cable rope guardrail has good economic benefit, social benefit and environmental benefit. The article puts forward the application condition of cable rope guardrail, and analyzes the factors of end extension, deformation, layout location, minimum setup length and initial tension of guardrail required to consider in the setup of cable rope guardrail, which provide the viewpoints for the popularization and application of cable rope guardrail in the highway safety and life protection engineering.
