    ANALYSE ON THE LANDSLIDE HAZARD AND ITS PREVENTION COUNTERMEASURE IN MOUNTAINOUS EXPRESSWAY

    • With the development of highway system in western China, more and more expressway has been built in mountainous regions. Many landslides may occur as a result of expressway construction, and could threaten the normal operation and safety of highway. In this paper, natural environment conditions and geological structural conditions of Yuanjiang-Mohei expressway in Yunnan Province are analyzed. Characteristics and risks of geological hazards along the expressway are studied. Their distribution characteristics and forming mechanism of landslides as well as its future development trends and control measures are also assessed. It is concluded that the landslides on mountainous roads are not only related to the engineering geological conditions, but also related to wrongful project designs and incorrect construction methods.
