【Abstract】 Through an investigation of engineering geology, the division of engineering geology has been made on the depression area of Beishan district in Dexin copper deposit, and five mathematical models have been established. At the same time, the calculation and analysis have been made using the limited-element mathermatical modeling method. Finally, the evaluation has been made on the stability of highway in the depression area.更多还原
