They were formed through regional isostatic adjustment and Theological flexure under the load of fold-thrust belts.
它是在褶皱冲断带负载的作用下，岩石圈通过区域性均衡调整及流变挠曲而形成的。

The key of calculating flexure strength of UPPC beam is to determine unbounded prestressed tendons ultimate value when the components are under their ultimate load ability.
计算UPPC梁(板)的抗弯强度，关键是确定构件在极限承裁能力时无粘结预应力筋的极限应力值。
