EQUIPMENT FOR FIELD DEFORMATION MEASUREMENTS

INSTRUMENTATION DEVICES FOR MAKING FIELD DEFORMATION MEASUREMENTS ARE SUMMARIZED. THE DEVICES, GROUPED IN ACCORDANCE WITH THEIR PURPOSE AND PRINCIPLE OF OPERATION, ARE TABULATED. SIMPLE PORTABLE DEVICES, SINGLE-POINT MONUMENTS AND VERTICAL TUBE SETTLEMENT GAUGES, MULTI-POINT VERTICAL TUBE SETTLEMENT GAUGES, SINGLE-POINT REMOTE SETTLEMENT GAUGES, MULTI-POINT REMOTE SETTLEMENT GUAGES, FULL PROFILE SETTLEMENT GAUGES, HEAVE POINTS, HORIZONTAL MOVEMENT GAUGES, INCLINOMETERS AND EXTENSOMETERS ARE BRIEFLY EVALUATED IN TERMS OF THEIR ADVANTAGES, LIMITATIONS, ACCURACY AND RELIABILITY. SCHEMATIC DRAWINGS WHICH ILLUSTRATE THE PRINCIPLES OF OPERATION ARE INCLUDED. BESIDES ACCURACY, A SPECTRUM OF FACTORS MUST INFLUENCE SELECTION OF AN INSTRUMENTATION DEVICE. THE IDEAL INSTRUMENT IS CHARACTERIZED BY ITS ABILITY TO ANSWER SPECIFIC QUESTIONS FOR THE FIELD ENGINEER; SATISFACTORY PERFORMANCE RECORD; SIMPLICITY OF DESIGN; DURABILITY; ACCURACY; ADEQUATE RANGE BOTH FOR CONSTRUCTION AND LONG TERM CONDITIONS; LOW OVERALL COST; CALIBRATION THAT MAY BE EASILY CHECKED AND MAINTAINED FOR EXTENDED PERIODS; INSTALLATION PROCEDURE WHICH CAUSES LEAST INTERFERENCE WITH NORMAL CONSTRUCTION PROGRESS AND CONSISTENT WITH THE CAPABILITIES OF AVAILABLE PERSONNEL; MINIMUM REACTION TO CHANGING ENVIRONMENTAL CONDITIONS; MINIMUM AUTOMATION; AND ITS POSSESSION OF A DATA ACQUISITION AND REDUCTION PROCEDURE CONSISTENT WITH THE CAPABILITIES OF AVAILABLE PERSONNEL AND EQUIPMENT.
