摘要
应用傅里叶级数方法,对与轴向力不在同一平面上的初始挠度对褶皱的影响进行了研究,结果表明:自由岩层褶皱时,只有一阶波对它有明显的影响,其他初始挠度对褶皱的影响不大,同时讨论了受约束岩层褶皱时初始挠度对它的影响,并指出只有某一特定波长的初始挠度(即它的波长等于或近似等于最终波长的初始挠度)才对岩层褶皱有明显的影响。
By Fourier series way, effects of initial deflections of rock stratum on folding of a single layer, whose surface is bevel to the axial pressure ( P )applied, have been studied; it is shown that only one order wave of the initial deflections affects on, the folding of the single layer with no restraint. And the effects of initial deflections on folding of restained layer were discussed as well, the results indicated that only initial deflection,whose wavelength is equal or approxmately equal to finally dominant wavelength, has an effect on folding of a single layer.
