Summary:Subgrade retaining structure is the most common structure of highway, once it is damaged by earthquake, its damage is universal. Under the action of seismic load, whether the subgrade retaining structure cracks or collapses, and the failure mechanism is one of the key problems in the design of retaining structure in earthquake area. Therefore, it is necessary to systematically study the typical failure mode, failure mechanism and seismic earth pressure of highway retaining structures. In this paper, through the investigation and analysis of earthquake damage law and failure mode of highway retaining structure, combined with numerical model test, the seismic damage mode of highway retaining structure is summarized, and effective seismic reinforcement method is put forward, which provides a certain basis for post-disaster reconstruction of highway structure.
