SLOPE STABILIZATION AND REPAIR OF LANDSLIDE DAMAGE

BOESCHUNGSSICHERUNGEN UND SANIERUNG VON RUTSCHUNGEN

FROM AUSTRIAN EXPERIENCE WITH THE STABILIZATION OF SLOPES IN GEOLOGICALLY DISTURBED ZONES AND MOUNTAINOUS TERRAIN, THE AUTHOR CONCLUDES THAT REFINED METHODS OF CALCULATION SIMULATE A DEGREE OF ACCURACY WHICH CANNOT BE OBTAINED IN PRACTICE. IN FACT, ONLY ROUGH STARTING POINTS CAN REALLY BE OBTAINED. OFTEN AN OPTIMUM FORM OF STABILIZATION CAN ONLY BE ACHIEVED IN A STEP-BY-STEP FASHION. THE NECESSARY CONSTRUCTIONAL MEASURES PRESENTLY USED ARE DESCRIBED AND EXPLAINED BY MEANS OF EXAMPLES. IN WET SLOPES DEWATERING BORINGS ARE MADE. FOR THE STABILIZATION OF COHESIONLESS MATERIALS LIME PILES MAY BE CONSIDERED, PROVIDED THAT THE FINE GRAINED PROPORTION OF THE SOIL IS CAPABLE OF REACTING WITH THE QUICK LIME FILLER. ROCK SUPPORTING SHELLS, SUPPORTING SLABS, RIBBED RETAINING WALLS, ARCH WALLS WITH FLYING BUTTRESSES, ALL SERVE AS PROTECTIVE MEASURES AGAINST LANDSLIDES. AN EXAMPLE DEMONSTRATES THE CONSTRUCTION OF A 14 M HIGH RETAINING WALL INSTEAD OF A SUSPENSION BRIDGE AS ORIGINALLY PLANNED; TWO FURTHER EXAMPLES SHOW THE CONSTRUCTION OF A CLOSED ANCHORED WALL, 15 M HIGH, ON A SECTION OF THE TAUERN MOTORWAY AND THE CONSTRUCTION OF A PILE WALL ON AN 800 M LONG STRETCH OF MOTORWAY IN SCHISTY TO PHYLLITE ROCK ON A SLOPE UP TO 50 M HIGH.
