随着我国公路建设步伐的不断加快,农村公路,特别是山区农村公路的安全保障工程问题日益突出。目前,国内针对国省干道公路安保工程建设具有较丰富的经验,但对山区农村公路安全保障工程的研究尚浅。本文针对山区农村公路较多出现的急弯路段,根据《公路安全保障工程实施技术指南》,并结合相关研究,提出了急弯路段的危险程度判别标准,并对不同危险等级的急弯路段采取了不同的安全保障对策,最后应用本文所提出的判别标准和安保措施,对广西省某县道的急弯路段进行了改造设计。
With the continuous acceleration of the pace of highway construction in our country, the problems of safety protection in rural roads, especially in mountainous rural roads have become increasingly prominent. At present, the country has rich experience in the construction of national security roads and highways, but the studies on the rural road safety guarantee projects in mountain areas are still shallow. In this paper, according to the Technical Guidelines for Highway Safety Support Engineering and the related research, aiming at the sharply curved sections of rural road in mountainous area, the criterion for judging the dangerous degree of the sharply curved sections is put forward and different sections with different dangerous levels are adopted Finally, the discriminant standards and security measures proposed in this paper are applied to transform the sharply curved section of a county road in Guangxi province.
