Abstract
For the design of impervious lining system of seepage tunnel, load-structure method and crack limit verification method are mostly recommended in China. However, the impervious design criteria is proved to be unreasonable for high pressure concrete lining system resulting in an over estimation of steel ratio. Thus, the research on a reasonable and safe permeable design for concrete lining of seepage tunnel is necessary. But, the suitable criterion is not confirmed in the design of high pressure hydraulic tunnel. Based on body force theory, a method of FEM is presented to design the permeable lining in high pressure hydraulic tunnel. The method can simulate the construction and security operation and repair process of the tunnel. The direct coupling of seepage field and stress field may be analyzed. Then, it is used in a real project. The crack width of concrete and the reinforcement of lining can be calculated by means of internal force. By comparison of the reinforcement, it is demonstrated that the results are satisfactory and the presented method is reasonable and effective.
