大红山铜矿矿区似大地水准面模型建设及研究

Quasi Geoid Model Building and Research of Dahongshan Copper Mine

完成大地水准面拟合方法的分析和曲面拟合的方法及对比情况分析,研究数据内插的理论和方法,提出方法的分析及对比情况,研究似大地水准面格网数值模型的理论和方法。根据GPS定位原理和大地测量学理论,对大红山铜矿矿区约20 km2区域的大地水准面的精化理论和方法进行了研究。GPS/水准几何法结合GPS水准数据及EGM2008模型"移去-恢复"法确定似大地水准面,针对大红山铜矿矿区高差大、地形变化激烈的实际情况,计算和比较已知公共点和检核点数据,计算研究大红山铜矿范围内的高程异常。

In this paper,fitting method of geoid was analyzed.A method and comparison of surface fitting were presented,and the theory and method of interpolation were studied.The theory and method of quasi ge-oid numerical model were also studied.According to GPS location principle and geodetic theory,geoid refined theory and methods of Dahongshan Copper mining area about 20 square kilometers area were studied.The ge-oid was determined by using GPS /standard geometric method with GPS leveling data and the “remove re-store”method of EGM2008 model.According to the actual situation in Dahongshan Copper Mine elevation, topographic change fierce,the known public point was calculated and compared.Point data were also checked.Height anomaly within range Dahongshan Copper was calculated.
