摘　　要：为论证鞍山地应力异常的可靠性，应用ＭＦ模型对其干扰和异常作了计算，发现１９９３年以来的长趋势及部分短期变化主要是干扰引起的，悬空元件和同期的室温、水位测值可作为其它受力元件的主要干扰因子．但在某些时段鞍山地应力仍有一定的趋势异常显示．In order to prove reliability of Anshan geostress anomalies and having applied MF model, it hasbeen found that long term tendency and some short term variation of them have mainly been due to interferencesince 1993. Temperature and water level are main interference factor. There still existed tendency anomalies forsome interval.
