EFFECTS OF SLOPE PROTECTION WORKS ON CRITICAL RAINFALL OF RAILWAY EMBANKMENT

Abstract

Embankment slope surfaces are frequently covered with protection works to prevent collapse by rainfall. In this paper, in the first we confirm effects of slope protection works on railway embankments through analyzing some past collapse cases in which the embankments were covered with protection works. Furthermore, we compare estimating critical rainfall of non-covering protection embankments with the actual rainfall after covering protection works, and shall try to quantitative evaluation for the protection works.
