However, most of the distribution of the earth pressure behind the flexible wall is of "R-shape" when the flexible wall experiencing "drum-shape "movement. Besides, the friction between the flexible wall and the soil is active during "drum-shape" movement, which decreases the deformation of the wall, lowers the application point of the resultant force and makes the development of the plastic in soil mass slow down.

研究结果表明，鼓型变位下柔性挡墙墙后土压力分布形式基本上为R字型；此外，墙土摩擦作用使墙体变位量变小，土压力系数降低，土压力合力作用点下降，塑性应变发展缓慢，从而提高墙体安全度。
