Abstract

Guardrail, as the last barrier to road safety, is an important part of road traffic safety facilities. Corrugated beam steel guardrail is the most widely used due to the advantages of simple replacement, easy construction, and good permeability. Currently, most of the corrugated beam steel guardrail is mainly used Q235 steel in our country. With further research and development of materials, the field of traffic safety facilities also gradually began to use new materials. High-strength steel is a new material with high tensile strength, when it is used for corrugated beam guardrail, using less material can achieve the same strength and stiffness as Q235 steel guardrail, thus making the guardrail lightweight. The reliability of the trial section with the new material guardrail needs to be evaluated before it is applied to the operational road on a large scale. To monitor the performance of the new material guardrail in the trial section, our research used numerical simulation analysis to verify the protective ability of high-strength steel guardrails car. Through the vehicle collision guardrail accident characteristics, the safety performance assessment index of high-strength corrugated beam steel guardrail is proposed, and the accident monitoring process, method, and data recording requirements are developed. In terms of durability, for high-strength corrugated beam steel guardrail corrosion treatment method, we summarized the technical points and requirements. For the trial section guardrail durability performance long-term monitoring, the specific process scheme, requirements and data recording, and other related requirements were developed. This study not only provides methods and guidance for the monitoring and evaluation of the use performance of high-strength steel guardrails but also provides support for the further development and application of new materials for corrugated beam guardrail.
