预应力在有限元分析中一般按等代荷载考虑，但体单元的预应力等代荷载计算很少见到讨论。
Prestress is converted normally into equivalent loads in the finite element analysis, but calculation of equivalent loads of prestress in body element is very few to be discussed.
以桥梁拱脚为例，依据实验结果提出了一种模拟预应力钢索与索道壁之间接触压力等代荷载的实用的方法。
Taking an arch foot as an example, a practical met hod was proposed to simulate the contact pressure of the prestressed tendon according to the experiment.
由微分几何基本公式导得圆弧曲线梁中预应力等代荷载的精确公式，预应力钢索在曲梁中竖弯与平弯均较平缓，此时公式可得以简化。
A precise formula for equivalent load of prestressing force in curved girder of arc form is derived from the fundamental formulae of differential geometry.
等代土层厚度法中破裂角为没有施加荷载时的角度，而施加上车辆荷载后破裂角必然发生变化。
The rupture Angle in the equivalent thickness of soil layer method is the Angle with no arrangement for the load. But the rupture Angle must change when the vehicle load is arranged.
