在介绍GPS高程测量原理的基础上，分析大地高与正常高之间的转换关系，以某隧道12期GPS大地高与精密水准测量数据为例，进行对比研究，验证了两种方法的实际精度。结果表明，GPS应用于区域沉降监测完全可以像精密水准测量一样高精度地反应监测点的沉降值，其结果精确、可靠。

Based on the introduction of the principle of GPS height measurement ,the conversion relationship between the geodetic height and the normal height has been analysed .Throught the data of 12 periods from a certain tunnel on GPS and precise leveling ,the comparative study has been done to verify the actual precision of the two methods .It shows that GPS applied to the regional subsidence monitoring can be as same as precise leveling and the result of GPS height is accurate and reliable .
