摘要
针对目前缺乏不同大变形等级下的TBM施工适宜性评价方法的问题,通过分析软岩大变形机理,总结大变形相关分级方法,考虑TBM掘进影响因素,建立软岩隧道TBM法适宜性分级标准,将其划分为非常适宜、适宜、较适宜、适宜性差、不适宜五个等级,并通过工程实例验证该方法的合理性,为软岩隧道大变形分级及TBM适宜性评价提供合理的参考依据,进而选择合适的施工方法和防治措施。
At present,the evaluation method of TBM construction suitability under different large deformation levels was lacking.The suitability classification standard of TBM method for soft rock tunnel was established by analyzing the mechanism of large deformation in soft rock,summarizing the classification methods,and considering the influencing factors of TBM tunnelling.It was divided into five classes:very suitable,suitable,more suitable,poorly suitable and unsuitable,and the reasonableness of the method was verified by engineering examples.This method could provide a reasonable reference basis for the classification of large deformation in soft rock tunnels and the evaluation of the suitability of TBM,and then selected suitable construction methods and prevention measures.
