HIGH FILLS RESTING ON RESIDUAL SOILS

THIS STUDY INVESTIGATES THE CAUSES OF A SERIES OF FAILURES WHICH OCCURRED WHEN A MOUNTAIN MOTORWAY WAS BUILT EXCLUSIVELY WITH HIGH FILLS RESTING ON NATURAL SLOPES, WHICH ORIGINALLY HAD A LO SAFETY COEFFICIENT. A SEARCH FOR COMMON CHARACTERISTICS OF FAILED FILLS HAS UNDERTAKEN IN ORDER TO FIND THE CAUSES OF THE SLIDES, AND LATER NUMEROUS FILLS WERE INSTRUMENTED. IT WAS ESTABLISHED THAT THE FAILURES WERE CAUSED BY THE RUPTURE OF THE RESIDUAL SOILS CONSTITUTING THE FOUNDATIONS. THE EVALUATION OF THE DATA OBTAINED MADE POSSIBLE THE ESTIMATION OF THE DRAINED IN SITY STRENGTH OF THESE RESIDUAL SOILS. IT IS CONCLUDED THAT EARTH-WORKS OF THIS NATURE, IF EXECUTED WITH A SUFFICIENT SAFETY COEFFICIENT, WOULD OFTEN PROBABLY BE MORE COSTLY THAN THE CORRESPONDING STRUCTURES, AND THAT THE CONSTRUCTION OF HIGH FILLS ON INCLINED SLOPES PRESENT SERIOUS DIFFICULTIES. IT IS EMPHASIZED THAT FOR HIGHWAYS OF THIS TYPE EXTENSIVE GEOMECHANICAL STUDIES OF THE FOUNDATIONS MUST BE COMPLETED. /TRRL/
