基于多元回归分析的泥水盾构施工参数分析

Multivariate Linear Regression Analysis of Slurry Shield Construction Parameters

盾构法施工技术在地铁工程建设中逐步得到广泛应用,对于盾构施工多参数的相关性分析研究更是少之又少,在这之中大多又是将土压平衡盾构作为研究对象,泥水盾构施工参数的多元线性回归分析几乎成了相关研究领域的空白。所以,有必要对泥水盾构施工参数的多元线性回归分析进行研究,从而保证施工过程的安全,降低工程造价,减少地铁施工的不利影响。本文以武汉轨道交通4号线左线757环到1460环的现场盾构施工数据,利用SPSS统计学软件对数据进行统计分析,建立起总推力和扭矩的多元线性回归模型,通过求解出的多元线性回归模型,对盾构施工工程中的总推力和扭矩进行预测。用右线的现场盾构施工数据进行工程验证,发现预测结果与实际结果吻合较好。

Shield construction technology is widely used in the construction of the subway engineering,but at present,domestic and foreign studies on shield tunneling parameters are comparatively less,among which most is about EPB shield. Research on multiple linear regression analysis of slurry shield construction parameters has become almost an empty field. Therefore,it is necessary to study multiple linear regression analysis slurry shield construction parameters to ensure the safety of the construction process and to reduce project cost as well as the adverse impact of subway construction. This article takes the example of the 757 to 1460 of the left line of shield construction data of Wuhan metro line 4,uses SPSS statistical software for statistical data analysis and establishes the multiple linear regression models of the total thrust and torque. The multiple linear regression models can be used to predict the total thrust and torque of the construction. With the right line shield construction field data for engineering verification,it is found that the predicted results are in good agreement with the actual results.
