UHPC-NC hybrid beam extradosed cable-stayed bridge and construction method thereof
The invention discloses a UHPC-NC hybrid beam extradosed cable-stayed bridge and a construction method thereof.The UHPC-NC hybrid beam extradosed cable-stayed bridge comprises at least one bridge pier, at least one bridge tower, a first bridge abutment and a second bridge abutment which are formed through NC pouring, a plurality of stay cables are arranged on the bridge tower, UHPC-NC pier top box girder sections are installed on the bridge pier, a plurality of prefabricated UHPC box girder sections are sequentially and tightly arranged in a main span area, and the first bridge abutment and the second bridge abutment are connected through a steel wire. A plurality of prefabricated NC box girder sections are sequentially and tightly arranged in the side span area, prefabricated UHPC-NC transition sections are arranged between the UHPC-NC pier top box girder sections and the adjacent NC box girder sections, and the UHPC box girder sections, the NC box girder sections and the UHPC-NC transition sections are connected with the bridge tower through stay cables. The UHPC-NC hybrid beam extradosed cable-stayed bridge has the advantages of being high in crack resistance, convenient to construct and good in economical efficiency.
本发明公开了一种UHPC‑NC混合梁矮塔斜拉桥及其施工方法，包括由NC浇筑成型的至少一个桥墩、至少一个桥塔、第一桥台和第二桥台，桥塔上设有多个斜拉索，桥墩上安装有UHPC‑NC墩顶箱梁节段，主跨区域依次紧密排列有多个预制的UHPC箱梁节段，边跨区域依次紧密排列有多个预制的NC箱梁节段，UHPC‑NC墩顶箱梁节段到相邻的NC箱梁节段之间设有预制的UHPC‑NC过渡段，各UHPC箱梁节段、各NC箱梁节段和UHPC‑NC过渡段分别通过斜拉索与桥塔连接。该UHPC‑NC混合梁矮塔斜拉桥具有抗裂性能高、施工方便、经济性好优点。
