Calculation of Normal Water Depth in the Standard Doorway Type Water Expressway Tunnel

CHEN Ping1,TENG Kai2(1.Water Administration Brigade of Qiqihar City,Qiqihar 161006,China; 2.Qiqihar Municipal Water Affairs Bureau,Qiqihar 161006,China)  
The standard form water section water depth to finish beyond normal calculation equation and not through the analytic method in solution directly.According to the present law,try algorithm and chart approximate method,the existing problems of the optimum fitting method,with the remaining poor standard minimum for target function,in engineering applicable range parameter,the fitting calculation and analysis for the more simple,intuitive expressions and a constant coefficient at least,digital digit is easy to remember and practical application,the calculation accuracy and meet the design requirements(maximum error is 0.685%) the approximate formula,has certain practical significance.
