| 1. | If viaduct approach spans are considered then perhaps the approach piers could be used to anchor the backstays . 如果设计中考虑高架引桥,则引桥的桥墩可用来锚定后拉索。 |
| 2. | Only 1, 000, 000 vehicle crossings produced significant cracking in the floor beams of the tied arch span and in the plate girders of the approach spans . 仅通过1,000,000辆车就在系杆拱的横梁中以及引桥的板梁中造成明显的开裂。 |
