| 1. | Cracking is almost completely avoided in prestressed concrete .
预应力混凝土几乎可以完全避免出现裂缝。 |
| 2. | Initially all structures were prestressed by high-strength bars .
起初，每个桥梁都是通过高强钢筋施加预应力的。 |
| 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 successful alternative was the cast-in-place segmental prestressed concrete box girder .
最后采用的方案是分段现浇的预应力混凝土箱形梁。 |
| 6. | 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。 |
| 7. | 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。 |
| 8. | They would certainly be less pleasing to the eye and often more expensive than the prestressed concrete beam .
与预应力混凝土梁比较，它们自然更显得外貌粗拙，不甚美观，而且成本也往往更高一些。 |
| 9. | 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。 |
| 10. | Anchorage , grip and coupler for prestressing tendons
预应力筋用锚具夹具和连接器 |
