The composite wing wall with staggered rigid wing wall and reinforced earth has fulfilled the requirement of stability against sliding and seepage.
采用刚性翼墙与加筋土间隔、上下错开的布置型式，形成复合式翼墙结构，满足挡墙的抗滑稳定性及防渗要求。

If we make a wing model which is similar to sliding mass, we can determine aerodynamic parameters by the wind tunnel testing and thus calculate the lift.
In the single-story house, sliding doors open the living and dining areas to the outside, while bedrooms are grouped in a longer wing of the L-shaped plan.
