| 摘要： | During the continuing evolution of integral and semi-integral bridges, some problems have been encountered by engineers not familiar with the peculiarities of these structures, or with standard bridge practices that have been developed over many decades for the achievement of trouble-free bridge construction. Problems that occasionally confront transportation engineers include early-age cracking of concrete bridge decks; erosion of roadway shoulders, embankments, and backfill adjacent to bridge abutments; casting connections between moving members; and stage construction errors. Those aspects of integral-type bridge construction that deserve particular care and attention are examined and discussed. Presumably, a better awareness of such background will aid transportation engineers to achieve the economy, quality, and outstanding durability that integral-type bridges make possible. |
