Where is stress,ε strain and the Young's modulus or elastic modulus

Strain Displacement Strain Strain field Strain determination in rocks

Review: 1.What is the orientation relationship between maximum shear stresses and principal stresses? 2. What are trajectories of principal stresses?

1.在地形地质图上求地质界面的产状 1.1求解条件 大比例尺地形地质图;测定范围内地质界面的产状稳定、界面平直连续

一、地质学的研究对象及任务 二、地质学的特征 三、地质学的研究方法

一、了解地质剖面图的图饰要素 二、掌握地质剖面图的编制方法

(A)General triaxial stress ellipsoid in perspective view. (B)Views normal to each of the principal planes of the ellipsoid. (After W.D. Means,1976)

1.地质体及其界面 1.1地质体的概念 地质体:各种成因的自然岩石体或土质体。 特点:形态各异,尺度多样,性状不同
