| 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。 |
| 9. | Anchorage , grip and coupler for prestressing tendons 预应力筋用锚具夹具和连接器 |
| 10. | Grout for prestressing tendons . test methods 预应力钢筋混凝土构件用泥浆.试验方法 |
