1 测量监理的提出 当年,在南浦大桥建造过程中由于实行了测量监理,使大桥总拼装获得一次成功。南浦大桥开工伊始并没有实行测量监理,后因测量方面的许多问题妨碍了工程进展而实施了测量监理。测量方面存在的问题和困难主要有: 1.1 原有测量控制网是按《城市测量规范》要求建立的四等三角网,它并不能作为大桥的精密测量基准,按照设计要求,主桥及主引 1, the proposed supervision of the survey year, in the construction process of Nanpu Bridge as a result of the implementation of measurement supervision, so that the total assembly of the bridge was a success. At the beginning of the construction of Nanpu Bridge, there was no supervision of measurement. After that, many problems in measurement hindered the progress of the project and implemented the measurement supervision. The main problems and difficulties in measurement are as follows: 1.1 The original measurement and control network is a quadrilateral network established according to the requirements of “Urban Measurement Specifications”. It can not be used as a precision measurement standard for the bridge. According to the design requirements, the main bridge and main guide
