静力触探曲线的分形分析

THE FRACTAL ANALYSIS OF STATIC CONE SOUNDING CURVE

静力触探曲线是一种常见的原位测试图形，由于该图形的不规则性及复杂性，长期以来，研究者们一直没有对它进行定量研究。本文从分形几何的观点出发，通过对静力触探曲线的变尺度测量实验，着重对测量结果进行了统计分析，结果表明，静力触探曲线是分形曲线，曲线分维成为反映曲线复杂程度恰当的统计特征量。同时指出，曲线分形维数与地层力学性质及硬层与软弱夹层数目密切相关，是地层沉积环境。

The static cone sounding curve is a common in situ testing chart.Investigator could not quantitively investigate into it for a long time for its abnormity and complexity.On the basis of fractal geometry ,and adopting the variable yardstick measure test method,statistically analyze the data form the test.The results show that the static cone sounding curve is a fractal curve. The fractal dimension of curve is the statistics character factors to reflect the complexity of curve correctly .Points out that the fractal dimension of curve is a synthetical reflection of the sedimentation and the mode of deposition.
