盐渍土盐胀性评价的组合赋权云模型应用研究

Research on Combination Weight Cloud Model Applied in Evaluation of Salt Expandability of Saline Soil

对盐渍土盐胀性进行评价,是盐胀病害治理的首要任务。规范及传统的评价方法中,不确定性(模糊性和随机性)对评价结果影响很大。为此,综合考虑主要影响因素,建立基于组合赋权的云模型评价法。以工程实例加以验证,结果表明:利用组合赋权云模型进行盐胀性评价是可行的,评价结果能准确有效地反映实际情况。

The evaluation of salt expandability of saline soil is the primary task of disease treatment. In the standard and the traditional method,the evaluation results are deeply influenced by uncertainty（ fuzziness and randomness）. In this case, based on a comprehensive analysis of main factors of salt expansion, the combination weight cloud model method is set up, and the feasibility of this method is verified through engineering example. Results show that it＇s feasible to use combination weight cloud model to evaluate the salt expansion,and evaluation results can reflect the actual situation accurately and effectively.
