珠穆朗玛峰峰顶大地水准面与似大地水准面差值计算及其验证

Comparion between geoid and quasi-geoid on the Mt.Qomolangma summit

本文利用登山路线上的实测重力点,通过试算分析确定了珠穆朗玛峰地区应采用的均衡模型及均衡深度,并利用该均衡模型推估了珠穆朗玛峰峰顶地形均衡重力异常与珠穆朗玛峰峰顶重力值。根据正常高和正高换算关系的需要,计算了珠穆朗玛峰峰顶沿垂线方向至黄海平均海平面的重力值的平均值与正常重力值的平均值,在此基础上完成了珠穆朗玛峰峰顶正常高和正高的换算,即大地水准面与似大地水准面差值计算,并对此结果采用其他方法进行了验证。

This paper introduces the computation procedure of mean gravity and normal gravity on Mt.Qomolangma by the plumb line to Huanghai mean sea surface.The conversion formula between geoid and quasi-geoid was established,and the difference was computed.The result was checked using the correlation method.
