Abstract: To provide scientific data for the design and construction, this paper evaluates in detail the existing or potential geologic hazards in the soft soil, swelling soil, liquefaction of sand, karst, deep cut, tall subgrade, and road building materials within the northeast area of the highway round Wuhan city. Various investigations and testing means (such as engineering geologic survey, drilling, penetration tests, geophysical exploration, testing and analysis) are used to compute and analyze all the engineering geologic problems and their harm on the highway, to forecast potential geotechnical problems during constructing and after completion, and to offer preventive measures and reasonable construction method.
