Simplified Method for Calculation of Shrinkage Depth in Tunnel with U-shaped Section

Teng Kai(Qiqihar Municipal Bureau for Water Resources,Qiqihar City 161006,China)  
as the typical U-shaped section consists of arcs with different radiuses,it is relatively complicated compared with other conventional sections.Calculation of the shrinkage depth not only fulfills solution with complicated transcendental equation but also provides the calculation formulas by sectional functions because the calculation cannot be performed directly by application of analysis method.But the conventional methods(graphology,trial method and iteration method) are complicated and numerous as well as with higher errors.In this paper,the transcendental equation resulted from transformation of the basic equations for the shrinkage depth at the section is replaced by the optimized fitting and the minimum typical remaining difference is considered as the objective function.In range of the applicable engineering parameters,the approximate formulas which are simple,direct and convenient for practical application as well as their calculation precision satisfies design requirements(maximum error,1.396%) are derived from the fitting calculations.These formulas are worth of developing for practical application.
