浅谈变截面空心薄壁方墩施工技术

Discussion on the Construction Technology of Variable Cross-section Hollow Thin-walled Pier

变截面空心薄壁方墩具有明显的优越性和较好的经济性，可以用较少的材料获取较大的截面抵抗矩，这种技术常常被山区、深沟建桥的工程所采用。本文以余家沟1号大桥为例，介绍了变截面空心薄壁方墩施工技术，可为类似工程施工提供借鉴。

Variable cross-section hol ow thin-walled pier has the obvious superiority and good economy, and can use less material to obtain larger sectional resistance moment which is often used by mountain bridge engineering. Taking the Yujiagou1# bridge as the example, this article introduces the construction technology of variable cross-section hol ow thin-wal ed pier, and provides reference for similar engineering construction.
