贵州省仁怀至赤水高速公路RCTJ-8合同段的桐梓河特大桥为(108+2×200+108)m四跨连续刚构桥,边跨现浇段采用非对称施工技术,工程应用实例表明:在山区复杂的地形地势、过渡墩较高的情况下,采用边跨现浇段非对称施工,不但能满足结构设计规范要求,并能缩短施工工期、降低工程造价和施工难度,也能保证施工安全。
The Tongzi River Super Bridge in RCTJ-8 Contract Section of Renhuai to Chishui Expressway in Guizhou Province is a four-span continuous rigid frame bridge of (108 + 2 × 200 + 108) m. Asymmetrical construction technology is used in the on-site cross-span casting. It shows that the asymmetric construction of side span and cast-in-site can not only meet the requirements of structural design norms, but also shorten the construction period, reduce the construction cost and construction difficulty in the complicated topography and transition pier in the mountainous area. Ensure construction safety.
