FULL-SCALE MODEL TESTS OF SLOPE FAILURE OF RIVER EMBANKMENTS

SLOPE FAILURE IN RIVER EMBANKMENTS DUE TO HEAVY RAINFALL AND FLOODING OCCURS FREQUENTLY IN VARIOUS PARTS OF JAPAN. IN ORDER TO CLARIFY THE PHENOMENON OF FAILURE AND TO ESTABLISH THE DESIGN METHOD FOR A STABLE EMBANKMENT, A SERIES OF FULL- SCALE MODEL TESTS WERE CARRIED OUT. TEST BANKS WERE BUILT SIMILAR TO THE ACTUAL EMBANKMENT AND VARIOUS KINDS OF DEVICES FOR OBSERVATION WERE INSTALLED. THE BANKS WERE THEN SUBJECTED TO SEEPAGE CAUSED BY ARTIFICIAL RAINFALL AND WATER LEVEL RISE UNTIL SLOPE FAILURE TOOK PLACE. THE READINGS OF THE MEASURING DEVICE WERE RECORDED CONTINUOUSLY DURING THE TESTS. THE OBSERVATION VALUES ARE ANALYZED TOGETHER WITH THE DATA FROM FIELD INVESTIGATIONS AT THE SITES OF SLOPE FAILURES. THE SLIDE WAS CHECKED WITH THE CONVENTIONAL STABILITY ANALYSIS AS WELL. THROUGH A SERIES OF FIELD TESTS THE STABILITY OF SLOPES UNDER THE EFFECT OF SEEPAGE COULD BE INVESTIGATED IN DETAIL, AND THE PHENOMENA OF THE DEFORMATION AND DESTRUCTION OF THE EMBANKMENT COULD BE CLARIFIED TO SOME EXTENT. /LCPC/RRL/
