摘　　要：边坡浅层溜坍与边坡冲刷是铁路路基边坡浅层破坏的主要表现形式,给铁路运营带来了巨大的安全隐患。本文总结了国内外铁路路基边坡浅层失稳与坡面冲刷分析方法,阐述了国内外铁路路基边坡坡面防护现状。日本针对边坡浅层失稳问题、德国针对坡面冲刷问题形成了相关的分析方法,中国既有规范尚未充分考虑降雨引起的边坡浅层稳定性分析。国内外坡面防护主要包括工程防护、生态防护,中国铁路路基边坡防护与国外相比圬工体量较大,坡面防护结构存在优化空间。Shallow slope collapse and slope erosion were the main forms of shallow damage to railway subgrade slopes,which would pose significant safety hazards to railway operations.This article summarized the analysis methods for shallow instability and slope erosion of railway subgrade slopes at home and abroad,and elaborated on the current situation of railway subgrade slope protection at home and abroad.Japan has developed relevant analysis methods for shallow slope instability and Germany has developed relevant analysis methods for slope scouring.The existing norms in China have not fully considered the analysis of shallow slope stability caused by rainfall.Slope protection at home and abroad mainly includes engineering protection and ecological protection measures.Compared with foreign countries,the quantity of masonry in China’s railway subgrade slope protection is relatively large,and there is space for optimization of slope protection structure.
