Working Methods of Fine Logging of Quaternary Geological Drilling in Urban Geological Surveying——Taking Urban Geological Surveying in the Leading Area of New and Old Kinetic Energy Conversion in Ji'nan as an Example
Finding out Quaternary stratigraphic structure is an important task of urban geological surveys in the coverage area, and drilling is an important means to obtain first-hand data. Geological records should be as detailed and accurate as possible. Urban geological survey work often serves the construction of urban engineering. Cataloging must not only meet the needs of Quaternary geological research, but also meet the requirements of engineering geology. In this paper, combining with the compilation experiences of the Quaternary System of the Urban Geological Survey Project in Ji'nan, lithology description methods of Quaternary geology and engineering geology, and the methods of field core photo shooting and indoor color correction processing have been summarized. It will provide some references for borehole cataloging during the investigation.
