| 高速鐵路路橋(涵)過(guò)渡段碾壓混凝土施工工藝研究(49 卷) |
| 英文標(biāo)題 |
| Construction technology study on application of roller-compacted concrete as subgrades filling material at bridge (culvert) transition section of high speed railway |
| 摘要 |
| 京滬高鐵三標(biāo)段橋臺(tái)和涵洞連接區(qū)多，施工量大，施工控制難度較大，擬采用水工碾壓混凝土和改性混凝土施工工藝改善過(guò)渡段剛度過(guò)大的問(wèn)題，使過(guò)渡段不僅具有一定塑性，而且降低工后沉降，確保高速鐵路在過(guò)渡段實(shí)現(xiàn)平順連接。 |
