【Abstract】 According to Rankine earth pressure model considering deformation presented by the author,the reduced coefficient of an active earth pressure is explored theoretically.The result shows that when the angle of the internal friction decreases or when the displacement of the retaining wall increases,the reduced coefficient of the active earth pressure decreases.In the end,the research results are confirmed by the experiment results of a centrifugal model test.更多还原
