摘 要: 應(yīng)用傅里葉級數(shù)方法，對與軸向力不在同一平面上的初始撓度對褶皺的影響進(jìn)行了研究，結(jié)果表明：自由巖層褶皺時，只有一階波對它有明顯的影響，其他初始撓度對褶皺的影響不大，同時討論了受約束巖層褶皺時初始撓度對它的影響，并指出只有某一特定波長的初始撓度（即它的波長等于或近似等于最終波長的初始撓度）才對巖層褶皺有明顯的影響。

Abstract: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.
Key words: fold initial deflecton fourier series rock stratum
