DETERMINING CORRECTIVE ACTION FOR HIGHWAY LANDSLIDE PROBLEMS

A STUDY WAS CONDUCTED IN WEST VIRGINIA TO PREPARE AN APPROACH TO THE ANALYSIS AND CORRECTION OF HIGHWAY PROBLEMS DEALING WITH LANDSLIDES IN UNCONSOLIDATED MATERIALS. IT WAS DETERMINED THAT THE BASIS FOR THE CLASSIFICATION OF LANDSLIDES SHOULD BE ON THE MECHANICS OF THE MOVEMENT RATHER THAN ON CAUSE AND EFFECT. SINCE FOR A GIVEN HIGHWAY- LANDSLIDE PROBLEM THERE ARE NUMEROUS SOLUTIONS THE PROBLEM CAN BE REDUCED TO A PROBLEM IN ECONOMICS. THE DETRIMENTAL EFFECT OF WATER HAS BEEN REPEATEDLY EMPHASIZED, BUT THERE HAS NOT BEEN SUFFICIENT EMPHASIS ON THE FACT THAT THE FORCE OF GRAVITY IS ALWAYS PRESENT AS A CONTRIBUTING FACTOR. ANALYSES OF A LANDSLIDE SHOULD BE GOVERNED BY A BASIC PRINCIPLE OF OBTAINING A MORE STABLE SLOPE THAN EXISTED PRIOR TO FAILURE. STABILITY ANALYSIS METHODS ARE DISCUSSED.
