Abstract

The main bridge of Anhui Huaiyuan Wohe River No 3 Bridge is steel pipe concrete tied arch bridge, adopted the construction method combining integral installation with asymmetric segmentation installation. It was locked in the abutment of arch to remove accumulative construction error. Concrete used in arch\|rib had the mixture ratio with such features as self\|floating, self\|planing and self\|compactablity to simplify the pouring method of steel pipe concrete.
