Rockfall Damage in a Mountainous Area to the Single Column Pier of a Bridge

摘要

In order to find out the damage caused by the impact of the falling stone on the bridge pier in the mountainous area of our country, the safety protection of the bridge pier of the mountain bridge in our country is provided with theoretical and practical technology. Using the finite element software that the nonlinear display power analysis tool LS–DYNA and damage constitutive model based on HJC, combined with the typical bridge pier on the highway line to study the damage of the single-column pier in the rockfall. The degree of damage to the pier column was analyzed by comparing the height, velocity, eccentricity, impact angle, impact surface and diameter and put forward protective recommendations.
