| 摘 要： | 依据非连续变形正分析方法的基本理论，提出了一种考虑多块体运动系统中特定块体边界允许适量侵入的方法－－子矩阵高速法，并给出了相应的调整公式。以青藏块体东北缘及其周围地区为例，考虑特定块体边界不同程度的侵入，模拟得到：（1）考虑侵入后，的确使模拟的结果得到明显改善；（2）用子矩阵调整法考虑特定块体边界适度侵入是切实可行的。

| Abstract: | On the basis of the discontinuous deformation positive analysis, the submatrix modulation method is presented to consider the appropriate invading of specific block boundary in many-block motion system, and the corresponding modulation formulas are given. This paper takes the northeast margin of Qinghai-Tibet and its surrounding area as the study area, and considers the invading of specific block boundary to different extent. The simulated results show: (1) After considering the block invading, the simulated results are more reasonable. (2) The submatrix modulation method is feasible for considering the appropriate invading of specific block boundary. |
