SETTLEMENT BEHIND ANCHORED WALLS - THESIS SUBMITTED TO THE FACULTY OF GRADUATE STUDIES AND RESEARCH IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE

WITH THE INCREASING USE OF ANCHORAGE IN EXCAVATION TECHNIQUES, PARTICULARLY IN URBAN AREAS, IT IS VERY USEFUL TO BE ABLE TO MINIMIZE GROUND SURFACE SETTLEMENT ADJACENT TO AN EXCAVATION. A STUDY OF SOIL AND ANCHORAGE PARAMETERS TOGETHER WITH SETTLEMENT, IS REVIEWED IN THIS PAPER. THE FINITE ELEMENT METHOD, WITH PLANE DEFORMATION CONDITIONS, WAS CHOSEN FOR THE STUDY OF THE EFFECTS OF THE ANGLE OF THE ANCHORAGE SYSTEM, ANCHORAGE LENGTH, PRESTRESSING FORCE IN THE ANCHORAGE, COEFFICIENT OF EARTH PRESSURE AT REST, YOUNG'S MODULUS OF THE SOIL FOR A TYPICAL EXCAVATION. IN ORDER TO VERIFY THE VALIDITY OF THE NUMERICAL METHOD, AN ANALYSIS WAS UNDERTAKEN FOR A GIVEN CASE; IT GAVE GOOD AGREEMENT BETWEEN OBSERVED AND PREDICTED SETTLEMENT. THE STUDY OF THE PARAMETERS SHOWED THAT THE SOIL CHARACTERISTICS (K INDEX O AND E) DICTATE THE MAGNITUDE OF SURFACE SETTLEMENT. THE GENERAL FORM OF SETTLEMENT HAS 2 MAXIMA. THE FIRST, LOCATED NEAR THE RETAINING WALL, IS NOT AFFECTED BY THE LENGTH OR DIRECTION OF ANCHORAGE, BUT IS REDUCED BY INCREASING THE PRESTRESSING FORCE. THE SECOND, LOCATED AT THE LEVEL OF THE GROUTED PART OF THE ANCHORAGE, IS ON THE CONTRARY NOT AFFECTED BY THE PRESTRESSING LOAD, BUT IS REDUCED BY INCREASING THE LENGTH OR DIRECTION OF ANCHORAGE.
