摘要
澳门轻轨1号线高架桥穿越凼仔岛中心区域,路线十分复杂,跨径类型繁多,上部结构采用短线匹配法预制和提梁机悬臂拼装新型施工工艺。文章阐述了施工及控制的关键技术。实践表明,节段预制拉装技术在城市高架曲线桥梁中适应性良好,对既有交通干扰少,施工效率高。
The viaduct of Macao LRT line 1 passes through the central region of TAIPA, the route is very complicated and thespan type is various. Its upper structure adopt new construction techniques of short-line matching prefabrication and cantilevererection by erection crane. We introduced the key technology of construction and control. The practice has proved that thesegmental precast assembly technology has good applicability in the urban viaduct curved bridge, less disturbance to theexisting traffic, and high construction efficiency.
