REGIONAL CONCEPT OF LANDSLIDE OCCURRENCE

THE REPORT COVERS THE INITIAL PHASES OF A BASIC STUDY OF LANDSLIDES. THE LONG-RANGE OBJECTIVE IS THE DEVELOPMENT OR REFINEMENT OF QUANTITATIVE METHODS FOR ANALYZING THE DEGREE OF STABILITY OF NATURAL SLOPES. THE UNDERLYING PRINCIPLE OF THE RESEARCH IS THAT THE TYPES OF LANDSLIDES THAT OCCUR IN A GIVEN GEOGRAPHIC REGION ARE RELATIVELY LIMITED AND THE NUMBER OF VARIABLES PRESENT IN A GIVEN REGION WILL BE REDUCED OR THE RANGE OF VALUES LIMITED. UNDER SUCH AN APPROACH A GREATER POSSIBILITY EXISTS FOR THE ESTABLISHMENT OF A COMPREHENSIVE GENERALIZED APPROACH. THE PHASE OF THE RESEARCH IN THE CURRENT REPORT COVERS THE BASIC CONCEPTS AND THE EFFORTS TO USE PHYSIOGRAPHIC PROVINCES OF THE UNITED STATES AS THE BASIS FOR REGIONAL CONSIDERATIONS. CASE HISTORIES FROM THE LITERATURE, FROM THE FILES OF THE AUTHORS AND FROM THE QUESTIONNAIRE RECIEVED BY THE HRB COMMITTEE ON LANDSLIDE INVESTIGATIONS WERE THE SOURCE OF DATA. THE LANDSLIDES WERE CLASSIFIED IN ACCORDANCE WITH THE NEW SYSTEM PROPOSED BY THE HRB COMMITTEE, AND A SUMMARY IS INCLUDED OF THE TYPES OF LANDSLIDES THAT OCCUR WITHIN THE SEVERAL REGIONS. POSSIBILITIES OF IMMEDIATE USE OF THE RESULTS ARE RECOGNIZED. IF THE TYPES OF LANDSLIDES THAT OCCUR WITHIN A REGION ARE LIMITED, THE HIGHWAY ENGINEERS IN A SPECIFIC AREA CAN LEARN MORE RAPIDLY AND ACCURATELY HOW TO ANALYZE AND TREAT THE LANDSLIDES ENCOUNTERED. /AUTHOR/
