多元线性回归分析在隧道施工抽排水定额编制中的应用

隧道施工中，涌水的抽排处理工序因影响因素复杂而导致定额测定结果差异性大。为提高定额测定方法的科学性、数据的准确性和成果周期的时效性，根据现场测定资料和对各定额影响因素敏感性的分析，划分定额子目，利用SPSS统计软件进行多元线性回归法分析处理样本数据，优化定额测定施工组织模型，并按分析成果进行定额测定数据的再平衡，缩短了施工定额编制周期，提高了施工定额数据的准确性和可信度。

Application of Multiple Linear Regression Method in Compilation of Norm of Water Pumping in Tunneling

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.
