Research on the Project Dregs Disposal in the Hilly Area and ValleyEnvironment Restoration along the Line in Shanxi Province

摘要

Dregs are often mass and distributed when we cosmically excavate tunnels and build roads in the hilly area under terrain condition in construction of water conservancy project. The dregs are bad for flood prevention of riverway and easily cause geological disasters because they are optionally dispersedly piled up in riverway and in the waste land of the bank, they will also aggravate soil and water loss and riverway silt, destroy valley environment, and arose a series of problem with no fit control. On the basis of practical instance of project, this paper brings forward basal principia of the project dregs disposal in the hilly area in Shanxi Province, gives a demonstration of the dregs disposal of hydraulic tunnel and roads construction in the first — stage of Wanjiazhai Yellow River Diversion Project, expounds the measure of project dregs disposal in the hilly area and valley environment restoration, finally evaluates and puts forward some proposals on the nowadays headway of dregs disposal and environment restoration. The results showed that these protection measures have some references for dregs disposal and valley environment restoration along the line in construction of the homologous projects.
