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。
The axial symmetry nonlinear finite element numerical simulation method was used to study the distribution of the inner pressure and the inner frictional force of the non-submerged cylindrical structure. Comparing with the experiment and the traditional method of calculating the inner pressure of the silo, there is a good agreement Sex. According to the existing test conditions, different foundation mats, different cylinder inner diameters and different filling conditions in the week were analyzed and compared.
