| Abstract: | The ventilation and heat elimination in the TBM construction are studied in this paper.By considering the duct fixing and the leakage of duct,several widely adopted duct leakage formulas were compared and discussed.With the theory of heat perforation,the function relationship between the temperature of the water and the distance of the pipe was obtained,then the water temperature could be simply calculated.A program for those extra-long tunnels,the ventilation and heat elimination during the TBM construction was complied with FORTRAN in the paper,and it could solve the problem accurately and rapidly. |
