数值波场正演在地震学和勘探地球物理学领域正得到越来越广泛的应用，用一个好的方法来建立一个复杂的地质模型则显得尤为关键。三角网格模型相对于层状模型和矩形网格模型在反映地质界面形态、三角网格剖分个数调节及射线追踪速度等方面具有明显优势。利用三角网格剖分的建模方法，在VC2008编程环境下实现了复杂地质模型的描述。通过对复杂模型的建模测试，表明采用三角网格剖分方法，可解决以下模型难题：①对复杂模型界面的描述；②对复杂逆断层的描述；③对封闭块体的描述；④对模型弹性参数进行描述。

The numerical wave field forward is more and more vastly applied in domains of seismology and exploration geophysics, us-ing a better method in a complex geological model formation is especially crucial. In comparison to layered model and rectangular grid model, the triangular mesh model has obvious advantages on geological interface imaging, triangulation number regulation and ray trac-ing velocity. Using triangulation modeling, has realized complex geological model description under the VC 2008 programming environ-ment. Through the modeling test of complex models has shown, using the triangulation, following model hard nuts can be solved:①de-scription of complex model interface;②description of complex reversed fault;③description of closed block;and④description of mod-el elastic parameters.
