摘要
文章针对广西三江波里一桥改建施工的实际情况,提出了桥梁半幅施工方案,并借助不同施工条件下成桥内力计算结果,探讨了桥梁半幅施工方案结构体系转换前后的内力变化情况,对比分析了半幅施工方案和整幅施工方案的成桥内力。分析表明,波里一桥半幅施工方案是可行的。
Aimed at the real construction condition of Sanjiang Boli No.1 Bridge in Guagnxi, the article proposes the haft side construction plan.Through the internal force analysis under different construction condition, it also discusses the internal force change before and after the structure switch and compares the bridge completion force for half side construction and whole construction.The analysis result shews that half side construction is feasible.
