【摘要】：以甘肃引洮一期工程9#隧洞为例,综合引入多层线性模型及数量化理论I的建模原理,在初始设置的解释变量基础上,通过逐步删除不显著解释变量的方法,建立了两层线性模型,对双护盾TBM的掘进速度的影响因素进行了研究。通过计算模型各解释变量固定效应的参数估计值,定量阐述了各因素对掘进速度的直接和间接影响,并依据模型的参数估计值结果对未来TBM的更好施工提出建议。通过预测模型和实例应用两方面分析、证明了该模型应用的可靠性,为同类工程掘进速度的合理预测和施工进度有效控制提供了理论依据。
[Abstract]:Taking the No. 9 tunnel of Yintao Phase I Project in Gansu Province as an example, the modeling principle of multi-layer linear model and quantitative theory I is introduced. On the basis of the initial set-up of the explanatory variables, the method of gradually deleting the inconspicuous explanatory variables is carried out. In this paper, a two-layer linear model is established to study the influencing factors of tunneling speed of TBM with double shields. By calculating the parameter estimation values of the fixed effect of each explanatory variable in the model, the direct and indirect effects of each factor on the tunneling speed are described quantitatively. According to the results of the model's parameter estimation, suggestions for better construction of TBM in the future are put forward. The reliability of the model is proved through the analysis of prediction model and practical application, which provides a theoretical basis for reasonable prediction of excavation speed and effective control of construction schedule for similar projects.
