RESEARCH ON PERSON'S FALL ACCIDENT ON SLOPE-TYPE REVETMENT BY HIGH WAVES

Abstract

  A person on a slope-type revetment at B coast in Hokkaido died due to run-up wave in November, 2008. In the present study, the meteorological data when the accident occurred were collected. In order to reproduce the situation of the fall accident on the slope-type revetment, two-dimensional hydraulic model tests and numerical calculation were carried out to examine the wave force on a human body.The fall limit ratio was newly proposed for estimating the qualitative risk of person's fall accidents.Based on these results, the safety height from water surface was shown with wave height and slope angle of the revetment.A basic idea of the safety management was also proposed for slope-type revetments.
