Analysis of Arching in Soil-Passive State
Abstract Arching involves stress transfer from yielding part of a soil to unyielding part of soil. Many authors considered arching action for active earth pressure. In this paper arching action is considered for passive earth pressure in noncohesive backfill. The backfill is assumed to move upward in a form of catenary arch due to arching. The value of θw (the angle of major principal plane) is calculated for soil-wall friction angle and soil friction angle. An expression for passive lateral stress ratio has been derived considering these angles. An illustrative example has been solved to show the effect on earth pressure distribution on retaining wall considering arching for different wall friction angles and soil friction angles. The applicability of proposed formulation is compared with model test results.
