武汉绕城公路东北段主要工程地质问题研究

STUDY ON MAIN PROBLEMS OF ENGINEERING GEOLOGY FOR NORTHEAST AREA OF WUHAN ROUNDING HIGHWAY

为了给项目的设计和施工提供科学依据 ,对武汉绕城公路东北段软土、膨胀土、砂土地震液化、岩溶、深路堑、高填路基、筑路材料等潜在的地质灾害进行了详细评价 ,通过采用工程地质测绘及钻探、触探、物探、试验分析等多种勘探、测试手段 ,对沿线的各种工程地及其危害表现形式进行计算分析 ,预测施工过程及工程建成后可能出现的岩土工程问题 ,提出了相应的施工方法 ,对同类工程的建设具有指导意义 .

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.
