为了闡明大地构造特征的成因,必須从地貭力学观点結合地貭发展史对大地构造特征的机理加以深入的研究。在作这些問題的研究时,必須以詳尽的地貭資料为基础,用力學观点进行分析。因此大地构造的野外研究具有首要的意义。但是野外的研究还不免有很多不足之处,在野外我們只能观察到地壳上岩石受到形变后的最終的靜止的結果,即我們所看到的岩层的产状、节理、断裂及其他构造形态;我們也只能凭这些所看到的岩石产状、节理、构造形态及相互间的关系通过各方面的对比来論証各阶段的发育情况(即变形过程),从而作出形成这一形态的某些力学条件。但是这些結論是带有假定性的。首先,在野外我們不可能观察到变形过程,而且尚未被我們所知的变形过程显然都被忽視了,因而就有必要在室內用模型法再造构造
In order to elucidate the causes of tectonic features of the earth, the mechanism of the tectonic features of the earth must be studied in depth from the perspective of geomechanics and the history of geoduck. In the study of these issues, we must analyze it on the basis of detailed information on the basis of mechanics. Therefore, the tectonic field research has the primary significance. However, there are still many shortcomings in the field research. In the field, we can only observe the final resting result of deformation of the rock on the crust, that is, the formation, joint, fracture and other structural forms of the rock formation that we have seen ; We can only rely on these see rock formation, joints, structure and the relationship between each other through various aspects to demonstrate the development of the various stages (ie, the deformation process), which made the formation of this form Some mechanical conditions. But these conclusions are hypothetical. First of all, in the field we can not observe the deformation process, and the deformation process which is not yet known to us is obviously neglected. Therefore, it is necessary to reconstruct the structure by modeling
