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。This study has developed two-layer linear models using a method of progressively deleting insignificant explanatory variables based on the initial explanatory variables specified and by applying the principles of hierarchical linear model and quantitative theory, and analyzed the factors that influence the penetration rates of double-shield tunnel boring machines（TBM） using the in-situ data of tunnel No. 9 of the Tao River diversion project phase I. We also quantitatively describe the direct and indirect impacts by these factors, using model parameter estimates for the fixed effects of each explanatory variable in the models; based on these estimates, suggestions for better TBM operation are put forward. The results indicate that our method is feasible in prediction of the tunneling penetration rates, and it would be useful for forecasting the construction progress and control management in similar projects.
