采用移去一恢复技术计算了济南市2．5’×2．5’分辨率的重力似大地水准面，并和布测的78个GPS/水准点所构成的高程异常控制网拟合，得到该区域的似大地水准面模型，将该模型似大地水准面高与由37个GPS／水；住得到的似大地水准面高进行比较，其差值的标准差为±1．8cm。

The gravitational quasi - geoid with 2.5 arc minute resolution is computed with remove - restore tech- nique. The quasi - geoid has been finished finally by fitting with the GPS quasi - geoid, constructed with 78 GPS/level- ing production. The modeled quasi - geoid were compared with the observed ones derived from 37 GPS/leveling data not applied to construction of Jinan quasi - geoid. The test results show that the standard deviation of the differences is ± 1.
