Stratified rock slopes are prone to damage under strong earthquake

leading to geological disasters such as crumbling

landslides and debris flow

and their stability evaluation and support structure optimization are key issues for engineering construction and academic research. Based on field investigations

theoretical analyses

numerical simulations and physical model tests in strong earthquake regions

scholars at home and abroad have carried out a lot of fruitful researches on the damage mechanism and reinforcement measures of rock slopes in strong earthquake regions. Starting from four aspects

including destabilization and damage characteristics of laminated rock slopes

types of support structures

reinforcement mechanisms of support structures and new seismic support structures

the research status of rock slope support structures under strong earthquakes is systematically reviewed

the shortcomings in the current basic research and technical methods of support structures are indicated

and the future research and development directions of seismic support structures for slopes are prospected. This study provides theoretical support for revealing the instability mechanisms and reinforcement strategies of stratified rock slopes in strong earthquake regions

while establishing a scientific foundation for developing more reliable support structures.
