【摘要】：中大比例尺重力勘查工作是各种物探方法中对大地测量精度(尤其是高程精度)要求最高的一种。近年来,在青藏高原地区开展的矿产地质调查项目中越来越多地应用了重力勘查手段,但由于青藏高原地区特殊的自然地理及人文环境,基础测绘程度低,因此,一些在人口稠密、经济发达的内地开展工作时常用的成熟大地测量方法在青藏高原地区已不方便或出现了新的问题。本文通过对青藏高原地区近年来开展中大比例尺重力勘查时测量工作遇到的实际问题进行梳理研究,结合具有针对性地方法技术试验成果,总结了一套解决问题的方法,可作为今后青藏高原及类似困难地区开展中大比例尺重力勘测时的参考。
[Abstract]:Large-scale gravity exploration is one of the most demanding geodetic survey methods (especially elevation accuracy). In recent years, more and more methods of gravity exploration have been used in mineral geological survey projects in the Qinghai-Xizang Plateau area. However, because of the special natural geography and humanistic environment in the Qinghai-Tibet Plateau, the basic mapping degree is low. Some mature geodetic methods commonly used in the densely populated and economically developed hinterland have become inconvenient or new problems in the Qinghai-Tibet Plateau. By combing and studying the practical problems encountered in the surveying work in the Qinghai-Xizang Plateau area in recent years when the gravity survey on medium and large scale is carried out, a set of methods to solve the problems are summarized in combination with the technical test results of the targeted earth methods. It can be used as a reference for large scale gravity survey in Qinghai-Xizang Plateau and similar difficult areas in the future.
