MATLAB在深层构造预测中的应用--以房山张坊水源地为例

Application of MATLAB in Deep Structure Prediction——Application in Fangshan, Beijing

利用MATLAB强大的分析能力,基于北京房山岩溶区浅层节理裂隙数据的进行性半自动化的统计与分析,绘制浅层节理裂隙玫瑰花图,并提取深层构造的走向线,最后与深层断层、向斜与背斜等构造进行拟合。拟合结果显示,北京房山岩溶地区浅层节理裂隙的统计走向与深层构造走向基本一致,北东向与北西向两条主构造方向的拟合误差分别为6.4%和2.1%。这一误差远小于设置的15%的误差容限,表明此代码在利用预测深层构造的应用中具有一定的正确性与潜力,能够为野外数据的分析统计提供简洁有效的帮助。但方法的有效性,仍需要通过更多的实例进行验证。

Taking advantage of the robust analytic ability of MATLAB, the analysis of shallow fractured joints in Fangshan karst area of Beijing were analyzed by a semi-automatic coding to draw the shallow joints, and extracted the deep structure trending lines. The results showed that the statistical trending of shallow joints in the Fangshan karst area of Beijing is basically the same as that of the deep tectonics, and the fitting errors of the two main tectonic directions are 6.4% and 2.1%, respectively. This error is far less than the 15% error margin of the set, indicating that the code has some correctness and potential in the application of predicting deep structure, which can provide a simple and effective help for the analysis and statistics of the field data, but the method’s effectiveness still need to be verified through more examples.
