Research On Design Theory Of Freezing Shaft Lining

On the basis of Research on design theory of freezing shaft lining,and integral analysis the design method for the Shaft Lining, especially when comparative research on every methods , the reliability level is considered; study the probability design metheod on the current code,obtained some drawbacks in the current structure design.According to a large amount of direct survey data,priori design experience and new code,in the paper,there have been worked out load standard value and distribution function and the shaft lining's resistance by means of probabillity and mathematical statistics.Using established limit state equations,the reliability index is checked by the"JC"method and the"C++"computer language.It is concluded that the calculation results is slightly above the aiming reliability.On the basis of its target reliability,probabitity design method for shaft lining is set up.It has good corelation with the probable design code. Development of design method for shaft lining from final value to probability has been realized.
