摘　　要：肖建华 ,陈至达 ,安里千 .用地震资料进行构造地压解释的理论基础研究 .石油地球物理勘探 ,2 0 0 2 ,37(3) :2 4 3～ 2 4 7从陈至达的有理力学理论出发 ,本文研究在极长周期低速变形体中的瞬间无限小平面波波动现象 ,论述了地震波的有效弹性参数是由地层介质的本性和当前变形状况共同决定的 ,进而探讨利用地震资料进行构造地压解释的有关理论基础。首先较详细地推导了一维有限变形运动方程 ,然后讨论其具体的解及有关计算公式。这一成果对于地震勘探技术中利用地震波场的演化信息进行构造地压反演解释有一定的可行性和实用价值。Taking Chen's rational mechanics as a theoretic basis, this paper studied wave phenomenon of transitional minimum plane wave in deformed media which have extremely long period and slow speed,expounded that the effective elastic parameters of seismic wave are determined together by intrinsic character and current deformation of formation and discussed the relative theoretic foundation of structure stress interpretation with seismic data. In the paper,wave equation of one dimensional limited deformation is derived in detail at first,then its specific solution and related computational formula are discussed.The results have some feasibility and practical value in using evolutionary information of seismic wavefield to carry out the structure stress inversion and interpretation in seismic prospecting.
