马林大桥变截面薄壁高墩施工技术

Construction Technology of Thin-walled High Pier with Variable Cross-section of Marlin Bridge

马林大桥处于深嵌V型峡谷中,峡谷两侧山坡陡峭,地形复杂。针对大桥主墩的超宽变截面空心薄壁高墩的施工技术,从施工工法、设备选型、垂直度控制进行总结,采取的施工技术具有较好的参考价值。

Marlin Bridge is located in embedded V-shaped canyon, with complicated terrain and steep slopes on both sides. In view of the construction technology of hollow thin-walled high pier with ultra-wide eross-seetion of the bridge＇ s main pier, this paper made a summary from the construction methods, equipment selection and verticality control, the technology used in the construction had a good reference.
