Abstract
JTJ074-94 was published in 1994 and revised in 2006. The biggest difference between before and after is the requirement of crash performance. In JTJ074-94, the anti-collision grade is B, and the anti-collision energy is 70kJ. In JTG/T D81-2006, the anti-collision grade is A, and the anti-collision energy is 160kJ. Because of the upgrade of the requirement of crash performance, the important question is to improve the protection capability of the guardrail in highway reorganization and expansion. However, the double w-beam barrier is the most domestic and applicable in many transformation methods, but the crash performance has not been proved. The protection ability of double corrugated beam barriers has been verified by simulation experiment. This simulation experiments also lay a foundation for the real vehicle crash test.
