一构造序次的概念构造序次是地质力学中的又一重要基本概念,也可称作世序(相当于英语中的generation)它是指同一岩块或地块中,同一方式的动力作用期间,产生的一连串的构造形迹,并具有阶段性。它们所反映的局部应力作用方式前后并不一致,但却密切相关。我们把构造形迹的这种成生顺序上的挨次控制关系称为序次。为了了解序次的概念,我们以背斜地堑的发展过程为例,看一连串构造形迹产生发展的序次。当水平产状的岩层遭受水平方向 CONCEPT OF CONSTRUCT ORDER Structure order is another important basic concept in geomechanics. It can also be called a sequence (equivalent to generation in English). It refers to the same mode of dynamic action in the same block or block Period, the resulting series of structural traces, and with the stage. The modes of local stress that they reflect are inconsistent but closely related. We call structural order of this order of birth and death on the order control relationship. In order to understand the concept of the first order, we take the development of anticline graben as an example to see the sequence of development of a series of structural features. When the level of horizontal rock formation suffered horizontal
