摘要
由于在实际隧道工程中,各级围岩的稳定性情况极为复杂,即使是同一级别的围岩,隧道稳定性也不尽相同。为了实现施工阶段围岩分级的可操作性与自动化,本文基于围岩稳定性对统一的围岩(岩质和土质)亚级分级理论标准及亚级分级方法的研究基础上,开发出相应的软件系统。该系统包括公路隧道围岩分级指标值输入、公路隧道围岩亚级分级、公路隧道设计参数确定和结果输出四大模块,实现了人机交互,同时还采用数据库对围岩的信息进行保存,使其应用更具人性化,操作更加简单。通过该系统的现场应用,其准确率可达85%以上,其计算结果可以为施工阶段的围岩分级及围岩变更提供一定的依据。
The stability of surrounding rock in each grade of rock is a very complex problem in practical tunne- ling. It is not the same even for the same grade of rock. In order to realizing maneuverability and automation of sur- rounding rock classification during the construction, the relevant software has been developed based on unified theo- retical standard and method for surrounding rock （ rock mass and soil） sub-classification considering the stability of surrounding rock. The software includes four modules： index input of surrounding rock classification, surrounding rock sub-classification, determination of design parameters of highway tunnel and result output. The data-base has al- so been adopted for convenient saving information of tunnels. It makes application more humanized and operation more simple. The accuracy has exceeded 85% by its in-situ application. So,the calculated results could provide evi- dence for surrounding rock classification and change during the construction of tunnel.
