STUDY OF THE NECESSARY ADHESION OF ANCHORAGE RODS IN ROCK AND SOIL ANCHORS

UNTERSUCHUNG DER ERFORDERLICHEN HAFTSTRECKE VON ANKERSTANGEN BEI FELS- UND BODENANKERN

THE PURPOSE OF THE RESEARCH WAS TO WIDEN THE KNOWLEDGE REGARDING THE SECURED LENGTHS OF ANCHORING RODS AND TAPPED BOLTS USING CEMENT AND SYNTHETIC RESIN MORTAR IN CONCRETE AND IN STONE. THE ASSOCIATED RELATIONSHIPS WERE STUDIED BETWEEN FORMATION OF THE ANCHORAGE ROD AND THE BOLT IN THE SECURED LENGTH, THE MORTAR CHARACTERISTICS AND THE MORTAR MOVEMENTS, THE SURFACE CHARACTER OF THE RECESSED OR BORED WALL, AND THE STRENGTH CHARACTERISTICS OF THE CONCRETE AND THE STONE. THE AIM OF THE RESEARCH WORK WAS TO FIND RELATIONSHIPS ACCORDING WITH THEORETICAL PRINCIPLES BY MEANS OF TESTS AND TO ARRIVE AT ECONOMIC SOLUTIONS FOR ANCHORAGE IN CONCRETE OR ROCK. THE TESTS ARE DESCRIBED AND THE EVALUATION RESULTS ARE ILLUSTRATED IN THE RESEARCH REPORT. A SUMMARY OF THE RELATIONSHIPS AFFECTING THE ANCHORAGE HAS BEEN PRODUCED WITHIN THE FRAMEWORK OF THIS RESEARCH WORK.
