The correctness and applicability of radial pressure calculation method for vertical shaft design suggested by specification of China should be validated.Based on the geologic informatics and parameters of some coal mine shaft walls,the theoretical distribution of radial pressure has been obtained by specification calculation method.Comparison of the measured value,it is found that the calculated result is not consistent with the measured value obviously,especially for rock stratum engineering;the error between measured value and calculated value increases with the depth of shaft wall increasing.Therefore,it is advised to study the mechanics of deep soil,and more tests and theoretical study should be carried out to analyze the radial pressure in deep alluvium.
