摘　　要：为了提高地下工程评判效率,利用三支决策的方法对地下工程岩体稳定性进行质量评判.首先利用模糊相对比较决策对地下工程岩体进行总体排序;其次通过贝叶斯决策规则做出期望损失最小的决策;然后用三支决策对地下工程岩体质量评判,得到分级结果;最后将该模型运用到实际工程中,验证该评判模型的科学性和可行性.为以后计算机在岩体质量评判中更为深入的应用打好理论基础.In order to improve the evaluation efficiency of underground engineering,the method of three-way decision is used to evaluate the stability of surrounding rock.Firstly,the surrounding rock of underground engineering is sorted by fuzzy relative comparison decision.Afterwards,the decision with the least expected loss is made by Bayesian decision rule.Then,the quality of surrounding rock of underground engineering is evaluated by three-way decision,and the classification results are obtained.At last,the model is applied to a practical project to verify the scientificity and feasibility of the evaluation model.It lays a good theoretical foundation for the further application of computer in surrounding rock quality evaluation.
