地壳上部的应力特征 1958年,瑞典学者哈斯特首次报道了采用套心法在瑞典等地测量地壳应力的成功试验。随后,他在欧洲、非洲等地进行了测量,试验证明,这种方法是可靠的。哈斯特对各地测量结果进行了统计分析,发现地壳中的水平应力大于垂直应力,某些地区甚至大于垂直应力几倍到十几倍。这一结论与当时流行的传统观点恰恰相反。因此,学术界对这一发现产生了强烈反映。 Stress characteristics of the upper crust 1958, the Swedish scholar Haste was the first to report the successful test of crustal stress measurement in Sweden by cerclage method. Subsequently, he conducted measurements in Europe, Africa and other places, the test proved that this method is reliable. Hastt conducted a statistical analysis of the measurement results around and found that the horizontal stress in the crust is greater than the vertical stress, and even greater than the vertical stress in some areas several times to ten times. This conclusion is contrary to the popular view of the time. Therefore, academics have strongly reflected this finding.
