基于层次分析法的综合超前地质预报及应用

综合超前地质预报是通过不同预报方法，在隧道施工中探明不良地质，降低工程风险的有效技术手段。不同预报手段的有效组合成为综合超前地质预报工作的关键，为了避免预报手段的随意组合、效率低下的问题，结合预报工程的实际情况，采用层次分析法及Yaahp软件进行多层次组合评价，定量化各种预报手段对预报最佳方案的权重，合理选择出以超前钻探为主，地质雷达、地质分析、TSP为辅的综合预报手段组合。经过城市地铁预报工作的实际应用，在应对地质环境复杂多变、环境影响因素较多的隧道预报中，显示了良好的效果。

Comprehensive Advanced Geological Prediction and Application Based on the Analytic Hierarchy Process

Comprehensive advanced geological prediction is an effective technique to detect bad geological features and reduce engineering risks in tunnel construction through different forecasting methods. The effective combination of different forecasting methods is the key to comprehensive geological prediction. In order to avoid the random combination of forecasting methods and inefficient problems, combined with current developments in forecasting engineering, AHP and Yaahp software were used to evaluate the multi-level combination, quantify the weights of the various forecasting methods to predict the best solution. A comprehensive forecasting combination methods is proposed, which focuses on reasonable selection of advanced drilling, and is aided with geological radar, geological analysis, and TSP, etc. The practical applications of the urban metro forecast are shown in the tunnel forecast for complex and changeable geological environments and other factors.
