PROPOSALS FOR THE APPLICATION OF THE PUCE PROGRAM OF TERRAIN CLASSIFICATION AND EVALUATION TO SOME ENGINEERING PROBLEMS

FOLLOWING ATTEMPTS TO MODIFY EARLIER LAND CLASSIFICATIONS FOR ENGINEERING USE, THE PATTERN UNIT COMPONET EVALUATION (PUCE) SYSTEM OF TERRAIN CLASSIFICATION HAS BEEN PROPOSED, BASED UPON EASILY RECOGNIZABLE AND DEFINABLE NATURAL FEATURES. THE SYSTEM RELATES ENGINEERING PROPERTIES TO THE TERRAIN AND ACTS FIRST AS A BASE FOR THE VALID EXTRAPOLATION OF TERRAIN PROPERTIES FROM ONE AREA TO ANOTHER, AND SECOND AS A FILE INTO WHICH ALL KNOWLEDGE OF ENGINEERING SIGNIFICANCE CAN BE COLLATED, STORED AND RETRIEVED FOR FUTURE USE. THE CLASSIFICATION SYSTEM HAS FOUR LEVELS OF GENERALIZATION, VIZ. PROVINCE, TERRAIN PATTERN, TERRAIN UNIT, TERRAIN COMPONENT, ALL OF WHICH ARE DEFINED AND, FROM THIS DEFINITION, EASILY RECOGNIZABLE. A BASIC PREMISE OF THE SYSTEM IS THAT ONCE THE PROPERTIES OF ONE EXAMPLE OF ANY MEMBER OF A CLASS HAVE BEEN ESTABLISHED, THEN THOSE PROPERTIES REMAIN SIMILAR OVER ALL OCCURRENCES OF THAT MEMBER. HENCE, WHILE THE TERRAIN REMAINS CONSISTENT, PREDICTION OF PROPERTIES CAN BE MADE. ENGINEERING APPLICATIONS OF THIS PRINCIPLE MAY BE MANY AND VARIED. PREDICTION IN TERMS OF THE APPROPRIATE LEVEL IN THE CLASSIFICATION COULD BE MADE OF: ROUTE LOCATION, GRADE LINE LOCATION, EARTHMOVING QUANTITIES, EARTHMOVING EQUIPMENT, BRIDGING AND CULVERTING FREQUENCIES, BEHAVIOR OF NATURAL MATERIALS AS SUBGRADE, LOCATION OF NATURAL MATERIALS FOR USE AS PAVEMENT CONSTRUCTION MATERIALS, AND BEHAVIOR OF NATURAL MATERIALS AS PAVEMENT CONSTRUCTION MATERIALS. THE MILITARY ENGINEER MAY FACE SIMILAR PROBLEMS IN CONSTRUCTION OF THE MANY FACILITIES REQUIRED BY AN ARMY. IN ADDITION HE MUST MAKE AN ASSESSMENT OF THE TRAFFICABILITY OF THE NATURAL SURFACE. THE PUCE PROGRAM OFFERS A BASIS FOR THE RECORDING AND EXTRAPOLATION OF EXPERIENCE OF GROUND MOBILITY ON LARGE AND SMALL AREAS OF TERRAIN. /AUTHOR/
