PROBLEMS ASSOCIATED WITH EARTH RETAINING STRUCTURES

All earth pressure theories put forward hitherto are based on an ideal, dry soil which is endowed with hypothetical, ideal, and uniform properties. This permits the engineer to solve earth pressure problems only approximately. By lateral earth pressure is understood the force which is exerted by the soil mass and which acts upon an earth- retaining structure, for instance a retaining wall or bulkhead, or sheet piling. The magnitude of the lateral earth pressure is known to vary considerably with the displacement of the retaining wall and with the nature of the soil. The effect of displacement of a retaining wall on the magnitude of the lateral earth pressure is best illustrated by Terzahi's paper on large-scale retaining wall experiments with dry and saturated sand as well as with fine-particled soils. These experiments revealed that the lateral earth pressure on a retaining wall varies with the lateral displacement of the wall. Theory, as well as experiments described by Prof. Junikis, shows that the passive earth pressure is always greater than the active earth pressure.
