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。

This paper studies optimal helicopter flight operations in the event one-engine failure. A three-dimensional point mass with a yawing motion of UH-60A has been used to study RTO and CTO from an elevated heliport or from a heliport, A first order dynamic of the OEI contingency power is considered. Flight after engine failure are formulated as nonlinear optimal control problems.

双发及多发直升机单发失效后，直升机飞行所需要的功率由剩余发动机提供，而在某些需要大功率的飞行状态时，如起飞状态、着陆状态等，剩余发动机提供的功率可能满足不了，这就需要对剩余发动机的可用功率进行合理利用。
