摘　　要：对我国跨断层形变观测干扰类型的统计分析表明,干扰因素主要是气象、地下水位、振动、荷载变化、人为干扰等,如降水量及地下水位的变化、观测点位附近施工等人为因素引起的点位上升或下沉;水库蓄水引起断层一侧负载变化导致高差变化;温度(气温或地温)、气压变化对地壳变形的影响等;外力及风力影响引起的振动等。The statistical analysis of disturbance types of cross -fault deformation shows that the interference factors mainly consist of meteorology, groundwater level, vibration, load fluctuation , human disturbance and so on. For example, subsidence and rise of monument may be caused by the variation of precipitation and groundwater lev- el or the human disturbance like construdtion nearby, the height change may be caused by the load fluctuation in one side of fault due to reservoir, variation of temperature and pressure can influence crustal deformation, and there are other interference factors like vibration caused by external force.
