摘要: 隧道围岩稳定性分级对隧道工程设计和施工具有重要的意义。利用影响隧道围岩稳定性的多种因素,应用投影寻踪评价模型建立隧道围岩稳定性分级方法,探讨了利用不便于量化为投影指标的影响因素对投影分级结果进行修正的方法。应用实例表明,投影寻踪分级结果与其它分级方法的结果相符,证实了方法的正确性。

Abstract: Accurate stability classification of surrounding rock mass in tunnel is very important to tunnel engi-neering design and construction.A projection pursuit stability classification method of surrounding rock mass is proposed based on multiple influence factors.The method of revising the result of projection pursuit classification is argued by using factors which are difficult to be took into consideration.Application example shows that the re-sult of projection pursuit classification is reasonable according to the result of other methods.
