THE INFLUENCE OF FOUNDATION WEIGHTS UPON EARTH PRESSURE ACTING ON FLEXIBLE STRUTTED WALLS

TESTS WERE CARRIED OUT ON A MODEL. THE PROCESS OF STRUTTING AND DREDGING IN OPEN EXCAVATION WAS SIMULATED. FOUNDATION LOAD WAS APPLIED BEFORE EXCAVATION STARTED. ACCORDING TO COULOMB, THE EARTH PRESSURE UPON STRUTTED RETAINING WALLS IS BIGGER THAN THE ACTIVE EARTH PRESSURE. THIS STATEMENT IS VALID WITH AND WITHOUT FOUNDATION LOAD. DEVIATIONS OCCUR CAUSED BY ACTIVE EARTH PRESSURE. EVEN UNDER THE INFLUENCE OF FOUNDATION LOADS, THE EARTH PRESSURE DISTRIBUTION DEPENDS MAINLY UPON THE DREDGING PROCESS AND THE POSITION OF THE STRUTS. ONLY LOADS ADJACENT TO THE WALL AFFECT THE PRESSURE DISTRIBUTION. EXAMPLES DEMONSTRATE THE RELATION BETWEEN THE DREDGING PROCESS AND EARTH PRESSURE DISTRIBUTION. DIMENSIONING AND DESIGN PROPOSALS FOR PRACTICE TAKING THE ABOVE RELATIONS INTO CONSIDERATION ARE PUT FORWARD. /TRRL/
