摘要:
提要:20世纪60年代,与板块构造学说建立的同时,在构造地质学中还有一项革新,就是变形构造分析的定量化,从定性描述走向定量计算。定量化的重要标志就是将力学中的摩尔圆引入构造地质学,并且使其改进和发展,在构造地质分析中建立了有限应变摩尔圆,适应了大变形的分析,又建立了极摩尔圆,适应一般剪切的分析。我国地质学家在其中也做出了自己的贡献。

Abstract:
Abstract:Simultaneously with the founding of the hypothesis of plate tectonics in the 1960s, another revolution, i.e. quantification of deformation structure analysis instead of qualitative analysis, took place. The important marker of the quantification is the introduction of the Mohr circle construction from mechanics into structural geology and improvement and development of it. The finite strain Mohr circle has been established for the analysis of large deformation and the polar Mohr circle has also been established in order to adapt to general shear deformation. Chinese geologists have made their due contributions.
