利用杆件大变形力学理论,对均质多岩层在力作用下褶皱的形成过程及结果进行了数值模拟,结果表明当岩层受力两端边界条件对称时,产生的褶皱是对称的;当边界条件不对称时,产生的褶皱是不对称的,揭示了对称与不对称褶皱产生的力学成因,同时也表明,大变形力学理论在地质构造模拟方面有着良好的应用前景。
Using the theory of large deformation mechanics of bars, the formation process and the results of the fold of the homogeneous rock under the action of force are numerically simulated. The results show that the fold is symmetrical when the boundary conditions of both sides of the rock are symmetrical. When the conditions are not symmetrical, the folds produced are asymmetric, revealing the mechanical causes of the symmetrical and asymmetrical folds, and also show that the theory of large deformation mechanics has a good application prospect in the geological structure simulation.
