| 摘 要： | 本用震源力学理论和方法研究了徐淮地区从１９７０年以来构造应力场的方向和强度的时空变化过程。结果表明：以唐山地震为分界线，本区的应力场Ｐ轴取向由震前平均６１．８°变为震后平均７７．７°。如果将本区以宿北断裂为界分为南区和北区两个部分，则北区的Ｐ轴取向从６８．１°变７１．２°，而南区的Ｐ轴取向由６２．５°变到８３．６°，南区的变化明显于北区。

| Abstract: | A dynamic boundary element--finite element coupling model is set up in the paperby combining the finite element and boundary element equations in establishment of thetime difference pattern in the Newmark approach. The efficiency both for solving the local domain problems in the finite element method and the infinite domain problems inthe boundary element method can thus be achieve(l simultaneously in analysis of dynamic response of a tbundatioll in time domain by using the coupling model. The 7 node super--parameter infinite element is employed in the domain integration of the boundaryelement method in the model. The numerical results of applications illustrate t.rtesatisfactory precision by using the model. |
