ON THE METHODOLOGY OF LANDSLIDE INVESTIGATIONS IN SOVIET RUSSIA

RUSSIAN INFORMATION IS PRESENTED ON THE LANDSLIDE INVESTIGATIONS DONE BY SPECIAL FIELD STATIONS LOCATED EITHER IN THE REGIONS WITH ABUNDANT SLIDES OR IN THE VICINITY OF A LARGE SLIDE IN A STATE OF SLOW MOTION IN WHICH FINAL FAILURE MAY OR MAY NOT TAKE PLACE. SLIDES ONLY, AS DISTINCT FROM FALLS AND FLOWS, ARE CONSIDERED. RUSSIAN APPROACHES TO THE SLIDE CLASSIFICATION ARE DISCUSSED FIRST, AFTER WHICH CRACKS AND FISSURES IN THE SLIDING BODY ARE CONSIDERED IN DETAIL. METHODS OF MEASUREMENT OF THE DISPLACEMENT AT SURFACE AND OF THOSE AT A DEPTH ARE DESCRIBED. THE PAPER ENDS WITH THE METHODOLOGY OF COMPUTING THE BALANCE OF SLIDING MASSES AT A GIVEN SLOPE, THE NEGATIVE BALANCE BEING GENERALLY AN INDICATOR OF THE TENDENCY OF THE SLIDE TO STABILIZE. /AUTHOR/
