| “铁跨公”立交桥涵封闭引道无人工缝设计与临界长度的确定(50 卷) |
| 英文标题 |
| Jointless design and determine of critical length for closed approach of highway culvert in condition of railway over highway |
| 摘要 |
| 为了防止“铁跨公”立交桥涵积水，将混凝土无缝设计理念应用到封闭引道设计中。从封闭引道自身特点出发，给出一种高性能混凝土配比设计，并通过有限元方法对其最大无缝长度进行了计算。结果表明，不均匀沉降和车载的作用不会引起封闭引道的破坏，其破坏主要与降温有关。在地 |
