Optimal Design of Low-Grade Highway Barrier
Aiming at the weak protection capability of current barrier in low-grade highway, an optimized barrier is designed and computed in this paper. The dynamic characteristics of vehicle in traffic accidents are simulated by LS-DYNA, and the performances of intermittent low-grade highway concrete barrier are improved by different shape, size and spacing. The final optimized barrier can orient vehicles and ensure vehicles do not roll or cross the barrier.
