Classification of granite weathering degree based on slope characteristics
摘要
Abstract
For solving the problem of quick dividing rock weathering degree by present remote sensing technology, a method for the classification of granite weathering degree based on slope characteristics was proposed by analyzing the coupling relationship between the granite weathering degree and the slope.Firstly, regional stratum lithology was interpreted by remote sensing data, and regional slope information was extracted by stereoscopic images.Secondly, the slope was divided into five grades, and the area percentages of different slopes in granite area was counted.Lastly, according to the characteristic curves of slope grade, the granite weathering degree could be classified.According to field verification, this method can correctly classify the granite weathering degree, which provides reference for engineering design and construction work.关键词
