| 摘 要： | 介绍粗糙集基本理论,建立基于大坝实测资料的以上游水位、下游水位、降雨量和气温为条件属性,以垂直位移测值为决策属性的决策表,首先采用布尔推理算法对决策表进行离散化,然后采用Rosetta软件进行约简,从中寻找决策规则,并以此为依据,进行垂直位移测值预测,所得结果与实测值吻合较好.实例分析表明影响大坝垂直位移变化的主要是温度和上游水位.

| Abstract: | An introduction of rough set theory is given;and a decision table which takes the temperature,precipitation,water levels of both upstream and downstream a dam as the condition attributes,while takes the amount of settlements of the dam as the decision attribute is created.The decision table is firstly discretized in the Boolean reasoning method;then reduced using a software called Rosetta.After the reduction,a series of decision rules are found out;and on the basis of these rules a prediction of the values ... |
