包西铁路黄河特大桥的测量控制
Baoxi railroad yellow river big bridge to measure a control especially
为了适应经济的发展，进一步的开发大西北，也为了缓解内蒙古包头及东胜地区煤炭资源外运的运力紧张问题，结合当地的经济技术地质等因素，决定在包头至西安修建一条新建铁路，本工程为双线客货共轨线路，设计时速250Km/h，在建的黄河特大桥位于本线路上，跨越黄河长度达3912.89m，在特大桥的建设中，测量工作显的尤为重要，关系到全桥的贯通，测量中使用全站仪及智能计算器，对点位进行精确测设，在实际工作中达到了显著的效果，而且加快了施工进度，节约了成本创造了效益。在本论文中将会较为详细的说明，利用先进仪器测设点位的方法，以及利用先进的方法实施桥梁工程中，各个细部的测设，达到了较好的效果。

ABSTRACT
    For the sake of orientation economy of development, further of develop greatly northwest, also for alleviate the head of Inner Mongolia pack and the east divine spot area coal resources outside carries of the luck dint nervous problem, combine the region of economic technique geology etc. factor, decide at the pack head to go to Xian to build 1 lately sets up a railroad, this engineering is a pair of track circuit with total goods, design soon the 250 Kms/h , in set up of yellow river especially big bridge being located on this circuit, cross over yellow river length to reach to a 3912.89 ms, in especially the construction of the big bridge, measure the work show of is importance, relate to whole bridgeses of run-through, measure in use the whole station instrument and intelligence calculator, carry on a precision to measure to establish to the point, come to a to show Zhao in actually the work of effect, and speed construction progress, economized cost to create a performance.Will compare for the expatiation in this thesis lieutenant general, make use of advanced instrument to measure a method of establish some, and make use of the forerunner's bridge engineering of the method implement in, measure of each minute part establish and come to a better effect.
