Study on Geodetic methods in Gravity Surveys of Middle-Large Scales Applicable to the Tibetan Plateau
摘要
Abstract
Among various geophysical methods,the geodetic methods in gravity surveys of medium-large scales have the highest requirements for measurement accuracy ( especially the elevation accuracy) . In recent years, the gravity method has been increasingly applied to geological and mineral re-source surveys in the Tibetan plateau area. Because of special physiographic and the human environments and low degrees of basic geodetic surveys availa-ble in this vast region, some mature geodetic methods that are commonly used in densely populated and economically developed areas cannot work well or encounter new problems. In this paper, we analyze such practical problems encountered in the Tibetan Plateau in recent years. In combination with the aimed test results of gravity surveys, we sum up a set of methods to solve these problems, which can be used as a reference for future surveys in the Tibet-an Plateau and the areas with similar natural conditions.关键词
