Rejia area,Baiyu,Sichuan is characterized by the development of dyke rocks wich were emplaced in groups and in zones into the Sayan Formation (T(1-2))and the Genlong Formation(T3).

The 3/4 length of the 110 kV transmission line along the Qinghai-Tibet Railway passes through the high altitude permafrost region,so the lightning activity and the soil geological condition of these regions will greatly affect the lightning protection function of the transmission line,and this should be considered in the design process.

Thermosiphon piles enable to increase the stability and bearing capacity of permafrost foundation and to prevent the foundation from frozen expansion and thaw settlement.

Based on modern technologies such as fuzzy mathematics,operations research,limit equilibrum theory and CAD technique,the method for optimizing waste disposal belt conveyor system in open pit mine is established.
