Research of Case-based Reasoning for Tunnelling Risk Using Rough Set
Lianxiang Zhang · Jisuanji gongcheng · 2008
As the complexity and uncertainty of the tunnel engineering,there is a considerable risk in the entire construction process.After investigating many history cases,this paper sums up these cases from four aspects,including question,scene,solution and result.To improve the efficiency and accuracy of case retrieving in case-based reasoning,the rough-set theory is introduced to reduce case attributes and get attribute weights.Compared with traditional technique,this technique reduces the subjective effects and improves risk assessment of the accuracy and efficiency,and guarantees the safety of the tunnel construction.
