摘要
本文提出一种基于现场位移监测和数值分析结合为地下工程提供预测的方法,利用现场量测的围岩或支护的位移-时间数据序列,通过相应的数字模型对未来位移发展作出定量预测。进而在预测位移的基础上应用数值方法预测支护的围岩压力,应力及安全度随时间的发展趋势。这种预测方法具有较高可靠性,可用于隧洞及矿山井巷的支护设计及施工效果的评价和安全预测.对于地下工程决策和科学施工有重要应用价值。已完成的监控-预测的应用软件可由一台微机在现场进行监测-信息处理和反馈分析-安全预测.
By combination in-situ measurement with numericalanalysis, the authorspresent a method for forecasting the safety of underground words. Form the measured displacement-time series of surround rock mass support and using an appropriate methematie model, the futural development of displacement can be forecasted, on such a basis, the tendency of furtural variations of the load, stress and safety of support(or tunnel lining)can be forecasted numericaly. This forecasting method can be used to evaluate the efficiening of construction and forecast the safety of tunnel lining of mining support with a high reliability. It is of importance for the correct decision and scientific construction of underground work.A software of monitoring-forecastion has been developed by the authors.Using a personal computer, it can fuefit the task of monitoring-information processing and feedback analysis-safety foracast in situ.
