This paper introduces the signif9cance of geoid refining and three methods for refining geoid, and by using the abnormal height of gps / leveling point, sets up several mathematic models of local geoid and makes the experiments and precision analysis
介紹了大地水準面精化的意義和精化大地水準面的3種方法，用gps /水準重合點的高程異常，建立了區域大地水準面的幾種數學模型並做了實驗和精度分析。 -
Now the 2d precision of spatial points is very great, but because by usual correlation fitting method we can transfer gps ellipsoidal height into normal height of the local geoid is considered as mathematical curve plane, it is not conform the fact of mountainous districts so the precision of elevation is so small that it is not satisfied with the requirement of leveling
目前，地面點的平面位置確定精度已相當高，但高程精度始終未能達到水準測量的要求，因為將gps大地高轉化為水準正常高的擬合推估方法是將局部大地水準面視為數學曲面，常常與實際情況差異較大（特別在西部山區差異更大） 。 -
In this paper, basing on many documents and the study of the former investigator, a new method of gps leveling being directly confirmed will be discussed in order to explore a method to improve precision ( which is centimeter or millimeter about the height anomaly ) of the engineering surveying, engineering construction and engineering research in the west mountainous districts of china ( for example yunnan province )
本文通過大量參考文獻的綜述分析，在前輩研究的基礎上，主要研究我國西部山區（以雲南高原山區為例）確定gps水準的新方法，目的是為西部山區找到一種快速、實時、自動獲取適合於工程測量、工程建設及工程領域科研的精度達到厘米級甚至毫米級的高程異常。 -
A description is made of the problems encountered in gps leveling measurement in this field and countermeasures. as observation of ground subsidence is made through measuring the relative movement of the observation stations, it is proposed to base the subsidence observation on change of geodetic elevation. check is made of the accuracy and reliability of this observation method by citing typical examples
介紹了gps水準測量中的若干問題及其解決方法，結合開采沉陷監測需要的是相對變化量的特點，為避免坐標轉換造成的精度損失，提出了開采沉陷觀測中的下沉值可應用大地高的變化量代替的方法，並對其精度及可靠性進行了實例驗證。 -
