摘要
文章从当前隧道建设实际出发,首先通过总结国内外多种围岩分级方法及采用指标情况,确立施工阶段以岩石坚硬程度和岩体完整程度作为分级基本指标,以地下水状态和主要软弱结构面产状作为分级修正因素的亚级分级指标体系,然后建立一种基于数量化理论的施工阶段岩质围岩亚级分级模型;并通过样本检验证实本模型具备较高的准确性和合理性,试图探索一种施工阶段围岩亚级分级标准;最后与编程技术和数据库技术相结合,进行施工阶段围岩亚级分级计算机辅助系统开发,以基本实现亚级分级的自动化和智能管理。
In light of the current reality of road tunnel construction, the sub-classification index system, which takes rock hardness and integrity as a basic index and groundwater status and occurrence of main weak structural surface as a correc- tion factor during tunnel construction, is established by summarizing the indexes of a variety of surrounding rock classifica- tion methods at home and abroad. A sub-classification model was also set up based on quantification theory. The sample test demonstrated that this model is highly accurate and rational. Combined with programming techniques and database technol- ogy, a computer-aided sub-classification system of surrounding rock was finally developed, which basically realized auto- matic and intelligent management of the sub-classification.
