摘　　要：The control value of the deflection of the embedded cylindrical structure, which is the maximum deflection allowed for stability of the cylinder, is a vital quantity of stability calculation. The deflection and the soil pressure on the embedded cylinder were investigated by model experiment. When the inclined angle of cylinder is less than or equal to 0.25°, the effective anti-overturning ratio increases gradually and reaches the maximum. When the inclined angle of cylinder is more than 0.25°, the effective anti-overturning ratio decreases gradually. The control value of instability of the cylindrical structure approximates 0.2°. and the bearing stress at the back edge of the cylinder is equal to zero.嵌入的圆柱的结构的偏转的控制值，它是最大的偏转允许柱体的稳定性，是稳定性计算的重要数量。嵌入的柱体上的偏转和土壤压力我们由模型实验的 reinvestigated。当柱体的使倾向的角度小于等于 0 时。25deg，有效打翻反的比率逐渐地增加并且到达最大值。当柱体的使倾向的角度是超过 0.25 deg 时，有效打翻反的比率逐渐地减少。圆柱的结构的不稳定性的控制价值接近 0。2 deg，和在柱体的背边的适用的压力等于零。
