摘要
龙场渡槽为钢筋混凝土拱式渡槽,该渡槽主拱圈采用全断面整体预制、缆索吊机配合斜拉扣挂系统的悬臂拼装施工工艺。简述了主拱圈的施工过程,并对渡槽拱圈施工过程进行数值模拟,合理确定各施工控制参数,确保施工过程结构受力合理,安全可靠。
The Longchang aqueduct is a kind of reinforced concrete arch aqueduct, whose main arch ring adopts overall precast full cross - section. The construction technology of cantilever assembly is adopted for cable crane with cable - stayed fasten and hang system. The construction process of main arch ring is discussed briefly, and the numerical simulation is performed during the construction of arch ring for aqueduct, so as to reasonably determine various construction control parameters and ensure the stress reasonability and safety and reliability of construction process structure.
