摘要
利用模糊数学原理,运用二元对比倒数法和专家调查法相结合,对路基基床状态进行评估。影响路基基床状态的因素包括组成基床的土质及密实度、线路年通过总重、轨道状态及水文条件。基床土质及密实度是影响路基基床状态的重要内在因素,在基床土质相同的情况下,密实度起主要作用,年通过总重次之。在确定模糊综合评判的各因素权重时,参加评价的专家愈多,得到的结果就愈接近实际。
The state of subgrade bed was evaluated by using fuzzy mathematics theory, the method of binary contrast reciprocal and in combination with expert investigation. Factors affecting the state of subgrade bed include soil and density of subgrade bed, the annual carrying gross weight of line, track state and hydrologic condition soil and density is the important internal factor affecting the state of subgrade bed. Under the condition of same subgrade bed soil, density plays the leading role, and the annual carrying gross weight takes the second place. On determining the weight of each fuzzy comprehensive factor, the more experts involve in the judgment, the result is closer to practice.
