新型柔性护栏设计与施工的应用性研究

Applicative Research of Neotype Wire Rope Safety Barrier Design and Construction

新型柔性护栏作为长湘高速公路"两型"科技示范工程的课题成果已完成实验研究、法规性实车碰撞验收及相关结题工作。基于该研究成果,提出了长湘高速护栏立柱、钢丝绳及锚端的设计方案及施工方法,并重点进行了锚端设计原理分析,以期达到该成果产品化和规范化要求,从而实现防护安全、生态和谐、资源节约的综合效益目标。

The wire rope safety barrier,which was achievement of science and technology demonstration projects in changsha-Xiangtan Highway,have been completed experimental study of the real car collision and relative test conclusion. Based on the research results,this paper proposes a design scheme of the guardrail post,wire rope and anchor and construction method, and put the emphasis on the analysis of the design principle of anchor end, in order to achieve the production and standardization of the requirements, so as to realize the comprehensive benefit target safety protection, resource conservation, ecological harmony.
