【摘要】 在钢管混凝土组合拱桥施工过程中,为了保证钢管混凝土拱桥成桥后结构的线形和强度要求,根据控制测量原理及技术要求,采用控制结构的受力与变形的方法对拱肋线形进行控制.舟山市新城大桥的工程实践表明,该方法运用恰当,施工方便,数据精度满足工程要求.
【Abstract】 In the concrete filled steel tubular arched bridge construction process, in order to guarantee that structure satisfies linear and intensity request after concrete filled steel tubular arched bridge is completed, according to control survey principle and the technical request, the method of controlling stress and distortion is used to control the line form of the arch ribs. The project practice of Zhoushan Xincheng bridge indicated that, this method is appropriate and convenient, the data precision satisfis the project requirements.
【Key words】 concrete filled steel tubular arched bridge; arch ribs; supervision and control the shape of line;
