| Abstract: | The paper proposes the conception of Beads type fold system. The mechanical analyses of the typical tectonicsystem are made by means of elastic stability theory, mathematical and mechanical method and rheology. Therelation among the deflections of folds and time, external forces, and distribution of Stresses, strain energy densityare analyzed to explain the causing mechanism of folding earthquake. |
