THE LANDSLIDE MECHANISM IN ALTERED VOLCANIC ROCK

THE MECHANICAL CHARACTERISTICS AND MOVEMENT MECHANISM OF LANDSLIDES IN VOLCANIC AND SEDIMENTARY ROCK WERE ANALYZED BY VARIOUS METHODS. COMPARISON OF THE RESULTS SHOWS THAT UNDER IDENTICAL CONDITIONS OF ALTERATIONS, SOME SEDIMENTARY ROCKS AND DEBRIS ARE TRANSFORMED INTO PLASTIC SOIL, WHILE VOLCANIC ROCK RETAINS SOME ELASTICITY. LAND SLIDES IN VOLCANIC ROCK OCCUR IN THREE MODES: (1) ROCK AND SOIL GLIDE (SEDIMENTARY ROCK); (2) LANDCREEP (IN DEBRIS); (3) SLOPE FAILURE (VOLCANIC ROCK). MODES 1 & 2 MAY RESULT IN SERIOUS DISASTER; MODE 3 IN ITSELF DOES NOT ENTAIL SERIOUS DANGER, EXCEPT THAT THE SLIDING MASS MAY SUBSEQUENTLY BE TRANSFORMED INTO DEBRIS AND UNDERGO LANDCREEP.
