【Abstract】 It is generally accepted that the soil pressure on cylindrical non-buried structure are closely predicted by the Jassen theory in harbor engineering. However many model test results have showed significant deviations form Jassen theory. In this paper, an axiymmetry finite element program with interface element is developed to simulate interaction between non-buried cylindrical structure and soil. The computed results of FEA agree well with that of model test. The soil pressure and skin friction distributions on cylindrical structure are discussed in detail on the different conditions.更多还原
