| “鐵跨公”立交橋涵封閉引道無人工縫設(shè)計(jì)與臨界長(zhǎng)度的確定(50 卷) |
| 英文標(biāo)題 |
| Jointless design and determine of critical length for closed approach of highway culvert in condition of railway over highway |
| 摘要 |
| 為了防止“鐵跨公”立交橋涵積水，將混凝土無縫設(shè)計(jì)理念應(yīng)用到封閉引道設(shè)計(jì)中。從封閉引道自身特點(diǎn)出發(fā)，給出一種高性能混凝土配比設(shè)計(jì)，并通過有限元方法對(duì)其最大無縫長(zhǎng)度進(jìn)行了計(jì)算。結(jié)果表明，不均勻沉降和車載的作用不會(huì)引起封閉引道的破壞，其破壞主要與降溫有關(guān)。在地 |
