摘要
在桃花吐短水准流动资料干扰因素研究的基础上，对该点台站水准观测资料作了排除干扰、提取异常信息研究。认为地下水位和冻土深度变化是该点跨断层测线高差变化的主要干扰源；该点水准趋势、短期异常不明显。对基岩标的抗干扰能力、干扰排除的复杂性等作了讨论。
Based on researching interference factor of mobile data of leveling at Taohuatu,eliminating interference and drawing anomaly message,we find that the ground water level and the change of frozen earth depth are main interference source of altitude difference change at fault crossing surveying line.There are not obvious short term anomaly of level trend at Taohuatu.The interference free ability and the complicacy of eliminating interference of bedrock bench mark are discussed in this paper.
