This standard is formulated to correctly identify and scientifically analyze the geotechnical categories, engineering characteristics and distribution of dredging areas, so as to improve the implementation level of dredging projects and strengthen technical management. This standard applies to the classification and engineering characteristics analysis of dredged rocks along coastal and inland rivers, as well as the necessary surveys and geotechnical tests for this purpose.
