跨越高速公路转体桥梁设计与施工控制

Design of Turner Bridge Spanning Freeway and Control of Construction

随着各地路网密度的不断提高,大量跨越已运营高速公路的桥梁建设工程日益增多,桥梁方案的选择尤为关键。其中平面转体施工桥梁因能最大限度减少对高速公路正常交通的影响,在跨线桥梁上的优越性也越来越明显。本文以一假想高速公路立交桥的建设,介绍平面转体桥梁的转体设计和施工控制。

As continuous enhancement of network density in all parts the large number of bridge projects spanning freeway operated are increased more and more, and choice of bridge building schemes is especially a key. In which the superiority of the bridge in plane turner construction over fly - over bridge is increasingly clear because it is enabled to decrease at maximum an impact on normal running of freeway. With building of a fictitious grade separation bridge on freeway, the paper introduces the turner design for plane turner bridge and the control of construction.
