某百万kW机组工程,为满足工艺布置要求,采用了栈桥穿烟囱的结构布置方案.在此方案基础上,建筑和结构专业进行设计创新,解决了由方案变动带来的技术难题.其中,结构专业采用的箱形大跨现浇钢筋混凝土栈桥结构,不仅解决了建筑防火问题,而且结构受力合理,节省投资,收到了良好的效果. In order to meet the requirements of process layout, the structure of a million-kilowatt aircrew project has been adopted. On the basis of this plan, the architectural and structural professionals are engaged in the design innovation to solve the technical problems caused by the program change, of which, The box-type, large-span, cast-in-place reinforced concrete trestle structure adopted by the structural professional not only solves the problem of building fire safety, but also has reasonable effects on structure, saves investment and receives good results.
