摘　　要：采用轴对称非线性有限元数值模拟方法研究了非沉入式大圆筒结构内侧压力、内侧壁摩阻力的分布规律；与试验及传统的圆仓内侧压力计算方法进行了对比，具有较好的一致性。针对现有试验情况，对于不同的基础垫层、不同的圆筒内径及周内不同的填土条件，进行了分析比较。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.
