地质雷达属性分析在浙江良渚莫角山红烧土层探测中的应用

应用地质雷达划分地层的主要依据是地层介质的电性差异，介质间的电性差异越大，地层界面越容易分辨。但在实际雷达探测中，某些介质虽然具有不同的电性参数，但会产生相同或相似的异常信号，这为地层划分工作带来困难。根据钻孔土芯测量出不同地层的电性参数，获取地质雷达探测的前提条件，对良渚遗址群莫角山红烧土遗址进行雷达数据采集，经预处理后分别进行常规数据处理和纹理属性提取分析，对比发现属性分析在地层划分上比常规处理方法更有优势。

Application of geological penetrating radar attribute analysis in the detection of burnt soil strata in Mojiao Mountain, Liangzhu, Zhejiang Province

The main basis of using geological penetrating radar (GPR) to divide strata is the electric properties of stratigraphic medium. The greater the electric difference between the mediums, the easier to distinguish the stratum interface. But in the actual radar detection, mediums with different electrical parameters could produce the same or similar abnormal signals, which brings a lot of difficulties for stratigraphic division. This paper measured the electrical parameters of different strata according to the borehole soil cores, which meets the preconditions of GPR detection. In comparison with the traditional analysis, the results of texture attribute analysis for burnt soils based on the processed GPR data-sets, acquired at Mojiaoshan of Liangzhu Site, demonstrate that the proposed method can achieve much better image for stratigraphic division than the traditional one.
