Numerical Analysis Methods of Drainage Structure for a Tailings Ponds
The design of drainage pipe structure is one of the most critical links in the design of tailings reservoir drainage system,and its safety is closely related to storage capacity.With the increase of land cost and the improvement of environmental protection requirements,many tailings ponds are faced with the demand for capacity increase.It is the most effective way to solve the problem of capacity increase to carry out fine calculation of drainage pipe structure and explore the potential of its carrying capacity.Based on the project of increasing the capacity of a copper mine tailings reservoir in Chifeng,Inner Mongolia,this paper adopts four kinds of analysis methods to solve the control internal force combination of the cross section of the drainage pipe according to the actual structure testing data and the basic idea of finite elements.The advantages and disadvantages of each method are analyzed,the calcu-lation results of each method are compared,and the accurate and efficient calculation methods suitable for the characteristics of the project are obtained,and the feasibility of its capacity increase is verified.
