| Abstract: | bridge was i Based on Wuliting bridge in Shaoguan, a new design and construction idea of composite beam-arch ntroduced. It was expounded that single row and variable cross section drilled pile with no pile cap was applied to the foundation; precast erection technology with striping and partitioning was applied to the beam; the section of bunching three steel tube was applied to arch rib of CFST, and a new construction method was in- troduced, in which arch comes after beam. The new idea is expected to be useful to the design and construction of similar structures. |
