摘要/Abstract

摘要：

以公路工程中的隧道为研究对象、指导工程安全施工与合理运营为目的，实现快速化、系统化、简洁化和人性化的操作为设计思想，从隧道围岩分级、围岩应力应变计算、围岩监测3个结构方面入手，利用Visual Basic开发工具，结合Office系列环境的“宏”命令，以Access为数据库平台，以Mschart控件和AutoCad接口控制图形输出，开发了公路隧道围岩稳定性评价软件，实现了计算、监测、编辑、有限元分析等多种功能。通过该软件在于木匠沟双连拱隧道工程中的应用，给出了隧道右硐K46＋014处围岩的级别为IV级，潜在破坏区域位于硐顶及硐底，围岩最终位移量为12.055 mm，并得到收敛位移与速率随时间变化的回归曲线。

Abstract:

Based on the objective of safe construction and reasonable operation，the study of three structural aspects：surrounding rock classification，analysis on the stress and displacement，surrounding rock monitor is performed with much attentions to the objects of highway tunnel by achieving the design ideas of rapid，systematic，concise，and user-friendly operations. By utilizing the development tools of Visual Basic，“Macro” command in Office and database platform of Access，the surrounding rock stability appraisal software for highway tunnel is developed with the calculation，monitoring，editing，finite element analysis and other functions，which controls the output of graphics by Mschart control and AutoCad interface. By using of this software in doublearch tunnel in Yumujiang gully，the surrounding rock of right tunnel at K46 +014 is given to be the grade IV，potential damage areas are given to be located in the top and bottom of the tunnel，the final displacement of surrounding rock is given to be 12.055 mm，and the convergence displacement-rate regression curve with time-varying is given.

Key words: tunnels, surrounding rock stability, surrounding rock classification, analysis on the stress and displacement, surrounding rock monitor, software development
