山区高速公路隧道围岩分级智能判别系统初探

Discussion of an Intelligent Rock Classification System for Expressway Tunnels in Mountain Areas

对于隧道围岩分级这类涉及到诸多影响因素的问题,利用计算机技术能避免人为因素带来的不确定性,可快速、合理地判定出围岩的级别。文章运用计算机编程语言和数据库技术,初步开发了一套山区高速公路隧道围岩级别智能判别系统,包括设计阶段围岩级别判别子系统和施工阶段围岩级别判别子系统。该软件系统界面清晰、操作方便,不仅可实现对围岩级别的定性与定量快速判定,还可实现对掌子面地质信息的查询、修改、添加、删除和报表打印等。此系统在四川西攀、攀田高速公路隧道围岩分级应用中取得了良好的效果。

As the classification of tunnel surrounding rock is influenced by many factors, the use of computer technology can avoid the uncertainty eaused by human factors and determine the classification of surrounding rock rapidly and properly. By means of eomputer programming language and database technology, an intelligent surrounding rock elassification system for expressway tunnels in mountain areas is developed, including two classifieation subsystems-one for the design phase and the other for the construction phase. With this software system featuring a clear interface and easy operation, it not only makes rapid qualitative and quantitative analyses of the surrounding roek classification, but also queries, modifies, adds, deletes, and prints the geological information for a working faee. In actual application, sound results have been obtained regarding the surrounding rock classifieation for the Xichang-Panzhihua and Panzhihua-Tianfang expressway tunnels.
