近来,Velde等人(1993)根据Moore等人(1990)先前所做的实验和绘制的图得到的数据,分析了裂缝轨迹。他们的基本结论是:封闭压力使应力引起的裂缝总体在空间均匀分布,因为在高压下某些空间分布特征的差异会减小。我发现这项工作很有意义,但我相信数据分析的结果不能支持他们的结论,而且数据本身就不符合处理方法。我重新分析了他们的一些数据,下面就讨论解释和与此相关的问题。 Recently, Velde et al. (1993) analyzed crack trajectories based on data obtained from experiments and plots previously made by Moore et al. (1990). Their basic conclusion is that the confining pressure causes the stress-induced cracks to be uniformly distributed in space as the difference in some of the spatial distribution characteristics under high pressure decreases. I find this work makes sense, but I believe the results of the data analysis do not support their conclusion, and the data itself does not fit into the process. I reanalyzed some of their data, the following discussion and explanation of the issues related to this.
