预应力全过程主要包括通过向与混凝土构件有关的筋施压从而达到向整合混凝土结构施加压力的目的。
The process of prestressing consists in applying forces to the concrete structure by stressing tendons relative to the concrete member.
特别在负荷方案中，一个附加的轴向前负荷可以趋向于增加压力、切应力和纤维强度。
An additional axial preload tended to increase the pressure, the shear, and fiber strains essentially for all load scenarios.
在建模过程中通过对容器壁内侧施加压力边界条件来模拟由于内充气体的作用在容器壁内产生的应力场，并通过与试验结果的比较验证了数值模拟方法的有效性。
The static stress wall resulting from the inner pressure was simulated by applying a stress boundary along the inner wall. A better correlation between experimental and numerical results was obtained.
