| 摘 要： | 基于拖带坐标法建立了岩层大变形的一维非线性微分方程，然后用解析与数值方法研究了变刚度、可伸缩岩层在侧向压力及自重作用下的分叉特性，初步揭示了褶皱岩层初始挠曲的形成机理。

| Abstract: | In accordance with the co-moving coordinate method,one-dimensional nonlinear differential equations for large deformation of a stratum are given in this paper. By using analytical and numerical solutions to the differential equations established, the bifurcation characteristics of a rigidity and length-changeable stratum.applied with an end load and its own weight,are studied.The form mechanism of initial deflection of stratum is brought to light initially. |
