A study on the stability evaluation of railway embankment under rainfall
초록
In order to evaluate the stability of railway embankment under rainfall, explanatory variables and subordinate variables wet-e selected for multivariate analysis. Furthermore the site which had occurred failure due to rainfall was investigated, and by executing multivariate analysis for 121 cases, critical rainfall was defined by the case that had high value of correlation factor. The maximum hourly rainfall during 24 hours before failure caused the collapse of railway embankment and could be used estimate the stability of railway embankment. From the result of application to a collapse example, the evaluation method by critical rainfall curve is satisfactory.
