摘要
为建立更为精确的裂缝几何形态数学模型适时预测裂缝几何动态,在前人工作的基础上,建立了分形效应下裂缝的延伸判据,改进了拟三维模型,并采用了Visual Basic 6.0软件编写了不考虑滤失情况下的改进后拟三维模型计算程序。同时,通过实例计算,得出了影响裂缝延伸的主要因素。
To create a more accurate mathematic model of fracture's geometric shape in order to predict its geometric dynamic,this study establishes the criteria for fracture extension under fractal effect,improves the pseudo-3D model,and programs the improved model without considering filtration using Visual Basic 6.0 Software.Moreover,the main factors influencing fracture extension are obtained by the calculation of an example.
