综合物探技术在浅层地质勘探中的应用
Application of Comprehensive Physical Exploration Technology in Shallow Geological Exploration
摘要
Abstract
Aiming at the strata with complex structure,changing geological conditions and difficulty in getting accurate geological information by a single geological exploration method,a detailed geological exploration test was carried out on the left bank of Yigong landslide by adopting physical exploration technology,including 80 mHz and 160 mHz ground-penetrating radar combined with high-density resistivity method,and the results show that the resistivity value in the depth range of the whole survey line showed the characteristics of higher resistivity at the upper part and lower resistivity at the bottom.The results show that the resistivity value in the whole testing depth range showed higher in the upper part and lower in the lower part,which can be regarded as a sign of gradual increase of water content;there was obvious layer demarcation in the buried depth of 4 m,and the left side of the testing line was the loose accumulation body of the landslide,which was more homogeneous,while the radar image on the right side of the testing line showed obvious reflective signals from the isolate body;in the depth of 60 m and 72 m of the testing line,the ground-penetrating radar appeared to have the same-phase axial interruption,and high-density electrical method also showed anomalies,which is supposed to be composed of different landslide terraces.It is assumed that the location consists of different landslide steps.The results of this comprehensive physical exploration provide an image basis for the geological analysis of the left bank of Yigong landslide,which is of great significance for the study of the structure of the landslide and the judgment of the potential hazardous area.关键词
