摘　　要：在选定稳定参考基准基础上，利用各种联测资料分离了地下水位变化对基岩标的干扰，剖析了三个台点基岩标的稳定性、主要干扰因素及排除方法，讨论了基岩标的设置条件。On the basis of determined stable referred datum, we eliminate the disturbing factors to the geoidal beacon originated from the variation of underwater levels in bedrock by using of many kinds of relative data. The stability of geoidal beacon, main disturbing factors and eliminating methods of three positions are analyzed, and also the fixed conditions of geoidal beacon are discussed.

关 键 词：基岩标稳定性 干扰因素 参考基准 地壳形变测量
