| 1. | Additional concentric prestressing was required in the pier .
墩内要求另加集中压力。 |
| 2. | The dimensions or prestressing force and eccentricity require modification .
尺寸或预加力和偏心需要修改。 |
| 3. | After closure, continuity prestressing tendons would be provided in the bottom of the box .
合拢以后，箱梁底部布置有连续的预应力筋。 |
| 4. | Suitable calibrated dynamometers were used to control the pull in the prestressing cables .
用合适的标定过的量测计控制预应力钢索的拉力。 |
| 5. | The prestressing influence coefficients depend on the geometry of the concrete structure only .
预应力影响系数仅取决于混凝土结构的几何形状。 |
| 6. | Later other prestressing methods with parallel wire or strand tendons were also used .
后来，又使用其它的预应方法，如利用平行钢丝或钢绞线施加预应力。 |
| 7. | Thus the use of these coefficients makes it easy to account for the variation in the prestressing force along the tendon .
因而，应用这些系数使得易于考虑预加力沿钢筋的变化。 |
| 8. | The concrete is subject to high compressive stresses and these are generally greatest when the prestressing is first applied to the concrete .
这种混凝土要承受高的压缩应力，而压缩应力一般在混凝土初次施加预应力时最大。 |
