本文着重论述了有关膨胀性软质围岩隧道的工程地质与工程建设的问题。根据工程实例,在不同方面与不同程度上分别阐述了岩土的特殊性质。在施工处理过程中,为设计提供了比较可靠的地质数据,从而改善了设计,制定出了新的施工方法,收到了较好的效果。同时参阅与引证了国内外有关的技术资料,进行了归纳与分析。结合实际情况,在定量性的判别指标方面提出了具体的建议。并相应的提出了勘测,设计、施工方面较为切实可行的方法。
This article focuses on the issues related to engineering geology and engineering construction of expansive soft surrounding rock tunnels. According to engineering examples, the special properties of rock and soil were elaborated in different aspects and in different degrees. During the construction process, more reliable geological data were provided for the design, thereby improving the design, formulating a new construction method and receiving good results. At the same time, it refers to and cites the relevant domestic and foreign technical data, and conducts induction and analysis. Based on the actual situation, specific recommendations were made on quantitative indicators. Correspondingly, more practical and feasible methods for surveying, designing and constructing were proposed.
