강우로 인한 철도 연변사면의 파괴특성: 현장사례 및 실내실험

초록

Slope failure triggered by rainfall produces severe effects on the serviceability and stability of railway. Since small amount of soil mass slipped on the rail can cause derailment which will induce great danger on the human and trains, slope stability problem is one of the major concern on the operation of railway. Field study(Sagong et al.,2005) shows four different types of slope failure based upon the morphology of the slipped slope triggered by rainfall. In this study, laboratory test was conducted to find out mechanism of four types of slope failure based upon field study results. From the tests detailed mechanism of four types of slope failure and the influence of the runoff water at the slope surface are understood.
