Safety Guardrail Design for Commercial Vehicle High Speed Track in an Automotive Proving Ground

某汽车试验场新建了商用车高速环道,用于55吨及以下轮式商用车辆道路试验。为了保障该特种道路正常安全地运行,需进行安全防护设计,其中就包含了安全护栏的设计。我们参考现行公路规范标准和国内已投入使用的同类型特种道路安全护栏结构形式,结合特种道路的用途和参数、现场所处的周边环境、汽车试验场以往事故发生原因等进行针对性的优化、加严、创新,完成了商用车高速环道的安全护栏设计并予以实施。

A new high speed track for commercial vehicles has been built in an automotive proving ground for the road test of wheeled commercial vehicles of 55 tons and below.In order to ensure the normal and safe operation of the special road,it is necessary to carry out safety protection design,which includes the design of safety guardrail.Referred to the current highway standards and the safety guardrail structural of the same type special roads that have been put into use in China,and combined with the usage and parameter of the special road,the surrounding environment of the site,and the causes of past accidents in the automotive proving ground,stringent and targeted measures of innovation and optimization were carried out to complete the design and implementation of the safety guardrail of the high speed track for commercial vehicles.
