摘要
波动分析方法认为沉积盆地的演化过程受不同的周期波所控制．实际应用表明：盆地内不同地区同一类同期波之间存在着差异，本文对造成这种差异的原因进行了分析，提出了应用这种差异解决盆地古应力场问题的研究思路和方法，应用这一研究方法对柴达木盆地第三纪古应力场恢复表明，压应力由南西220°向北东40°方向传播。
The method of the Undulation Analysis believes that the evolutionary process of a depositional basin is controlled by different cyclic waves. Practical application shows that there are differences between the same types of cyclic waves in the different regions of a basin. In this paper, the causes which result in such differences have been analysed, and the research thinking and method using the differences to solve the paleostressfield problems of basin are suggested. The restoration of Tertiary paleostressfield in the Qaidam Basin by means of this method indicates that the compressive stress spreads from SW220°to NE40°
