FIELD MEASUREMENTS OF LATERAL EARTH PRESSURES ON A CANTILEVER RETAINING WALL

This paper presents results from a research study on determination of lateral earth pressure for use in retaining wall design. The broad objective of the study is to develop improved design procedures for retaining walls. The limited objective of the phase of the study covered in this paper is to measure the pressure acting on a typical cantilever retaining wall and to compare the measured pressures with theoretical pressures determined by Rankine and Coulomb theories. Tarra Tec pneumatic and Geonor vibrating wire pressure cells were used to measure lateral earth pressures. Procedures used to calibrate the pressure cells are presented. Measurements of the lateral movement of the wall were made during and after backfilling. Data covering a period of 14 months are presented. These data include graphs of earth pressure and wall movement versus time and graphs of pressure distribution versus depth. Engineering properties of the backfill materials are presented. Computed earth pressures based on the Rankine and Coulomb active case are compared with measured pressures. A significant finding is that the measured pressures near the base of the wall are higher than the active pressures. They are nearly equal to the at-rest pressures that are possible as a result of the small movements that occurred at the base of the wall.
