【摘要】 为了减小传统方法布设公路桥梁设计、施工控制网的外业工作量和内业计算的繁杂性,运用红外测距仪或全站仪布设公路桥梁测边网,采用条件平差的计算方法,建立条件方程式和法方程式,计算各边角的平差值。应用实例表明,公路桥梁测边网的布设与计算精度满足有关技术规范要求,便于公路工程技术人员现场应用和计算。更多还原

【Abstract】 When setting the control network of the design and construction in the highway bridge by the traditional method, the outside work is heavy, and the calculation is complicated.In order to overcome those problems, this paper developed a new method. With this method, firstly establish the survey-trilateration control network in the control survey of the highway bridge with infrared range finder or total station; then set up the condition adjustment and normal equation by using the calculate method of condition adjustment; lastly get adjustment value of every side corner. This new method was applied to an engineering practice, it was found that the survey-trilateration control network in the control survey of the highway bridge and calculate precise can meet the needs of the adjustment theories, and it is convenient for the technical engineer’s calculating on the spot. 1 tabs,3 figs, 7 refs.更多还原
