| 摘 要： | There are two kinds of superposition in the tectonic deformation of the crust, compound superposition and combined superposition. According to the principle of superposition of elastic theory, the tectonic stress field caused by two or more systems of external forces, acting on a block at the same time, equals superposition of the individual tectonic stress-field produced by the action of the forces applied individually. A group of formulas of stress superposition are given, and the superposition of homogeneous and inhomogeneous stress-fields are analysed. The geometric property and features of deformation of combined structures are explained in this paper.
