Abstract: In recent years,successively ground motion in the xian,region has aroused extensive scientistific interest.Based on the relationship between the time series of dislacation in vertical,horizontal and extensional derections,and the time series of various factors in the same period,using a regression analysis.It is found that the motion of Xian ground fissure in the study region is not only confined by geoteetonics but also related intensive decline of confined groundwater.This paper will bring us a new approach to the study of ground fissures in the xian region.

摘要： 本文根据大量实际观测数据运用逐步回归分析方法,对西安地裂缝在垂直、水平,引张三个方向上运动的时间序列及各种因素在相同时期内变化的时间序列之间的关系进行计算分析,发现了与地裂缝运动有关的因素。从而论证了西安地裂缝的运动除受地质构造条件的控制外,也与承压水水位的剧烈下降密切相关。利用此方法试图对西安地裂缝研究开拓一个新的途径,从而为地裂缝的理论研究,提供重要依据。
