摘要
以杭州望江路过江隧道盾构段为工程背景,选取地质情况相对单一的粉砂、淤泥质粉质粘土夹粉砂复合地层为研究对象,统计该段地层的盾构掘进参数,对各参数进行两两相关性分析,建立关于推力的多元回归方程,并验证,结果发现推力拟合值与实测值总体变化趋势是一致的,但精度有待提高。
This paper takes the advance parameters data of the 190 to 369 ring of the shield which is working on the right line of Hangzhou Wang-jiang rood tunnel as research.Using SPSS software to analyse the statistical parameters data and established the multivariate linear regression function of thrust force.The verification result indicates that the fitted curve shows the similar trend of the measured value of thrust force.However,the precision of the regression model needs to improve.
