本文根据非均匀破裂圆盘位错模式在均匀介质中给出的远场位移解,通过直角坐标系的正交变换,导出了一组震源节面方程。其中,P波理论地震图的计算,考虑了介质的非弹性吸收和仪器暂态特性的影响。节面方程采用球面量板求解:取4个台的(?)折算振幅比,直接拟合其辐射图型因子,即可在球面上求得震源两个节面。最后,用本文方法分析了新丰江水库区一个中等强度的震例,所得断层面解与按(?)初动符号分布确定的结果甚为接近。
In this paper, according to the far-field displacement solution given by the dislocation disk inhomogeneous dislocation mode in a homogeneous medium, a series of equations of source nodal plane equations are derived by orthogonal transformation of rectangular coordinate system. Among them, the calculation of the P-wave theoretical seismogram takes into account the inelastic absorption of the medium and the influence of the transient characteristics of the instrument. The nodal equation is solved with a spherical volumetric plate. Taking the (?) Converted amplitude ratio of 4 stations and directly fitting the radiation pattern factor, two nodal planes of the source can be obtained on the spherical surface. Finally, by using this method, a case of moderate intensity in the Xinfengjiang reservoir area is analyzed. The result of fault surface solution and the initial sign distribution of (?) Is very close.
