active earth pressures, seismic earth pressures, design of retaining structuresAbstract
In retaining structures with a back inclined more that a certain critical value, active earth pressure coefficients can not be directly determined using the classic earth pressure theories. They should be determined using a procedure involving the sum of two forces (a soil weight and an active earth pressure force, both affected by seismic coefficients, when such action needs to be considered). For design purposes, the direct determination of the force acting on the back of the retaining structure may be useful, as it replicates, with the necessary adaptations, the usual procedure valid for inclinations of the back of the retaining wall less that the critical value. In this Technical Note, it is shown how such earth pressures can be easily determined and programmed.
