Due to the complex influence factors in water pumping during tunneling, the measurement result of the water pumping normal has great difference. In the paper, the sensibility of each influence factor is analyzed, the sample data is analyzed by means of SPSS multiple linear regression method, the construction organization model of the measuring is optimized, and the measuring data is rebalanced on basis of analysis results, so as to improve the scientificness and accuracy of the measuring data and the timeliness of the result period. In this way, the norm compilation period is reduced, and the accuracy and reliability of the data of the norm are improved.
