摘    要：讨论了岩层初始挠度对单层褶皱的影响;运用数理理论求出自由岩层褶皱的挠度微分方程以及临界轴向压力p与岩层弯曲的褶皱波阶数之间的关系,从而说明了在自由岩层受力褶皱时,与轴向力在同一平面上的初始挠度以一阶波影响最大.这对进一步研究岩层的褶皱变形有一定的理论意义.

Abstract: The effects of initial deflection of rock stratum on folding of a sinle layer have been studied. According to materials mechanics and elasticity, the differential equation relating to the deflection and relation of critical axial load (p) and quantities of orde-waves of rock stratum of folding, it is shown that on the same plane of the initial deflection of rock stratum and the critical axial load (p). the effects of one-order wave of the sinle layer folding is greater than others on the free rock stratum.
