| Abstract: | Based on the road damage data and damage phenomena of Wenchuan earthquake in 2008, the relevant factors of the earthquake damage of road components (retaining walls, slopes and subgrade pavement) are collected, the statistical results are analyzed macroscopically, and then different damaged modes of road components are classified, the common natural geological conditions and engineering factors of each type of damage are summarized. In view of its natural and engineering factors, the occurrence mechanism of earthquake damage phenomena of road components (retaining walls, slopes and subgrade pavement) under earthquake action is given, which helps to understand the damage characteristics of traffic systems. Appropriate measures are taken according to objective conditions to improve the earthquake resistance ability and recovery ability of road after the earthquake. |
