摘　　要：根据试验结果及分析 ,圆筒内填料抗倾模式随筒径的增大而变化 .筒径由小到大 ,筒内填料抗倾模式由重力式逐渐向过渡式、平面挡土墙式变化 .大圆筒的抗倾能力 ,除应考虑筒内壁与填料间的摩擦力 。Based on experimental results and analyses, it can be seen that the anti inclination model of inside filler varies with the diameter of the cylinder, and that the model type ranges from gravity to transitional and to plane retaining wall when the diameter of cylinder increases. The inclination strength of large diameter cylinders includes the lateral pressure of inside filler acting on the cylinder wall as well as the frictional force between inner wall and filler.
