摘要
提出了一个土体冻胀灾害预测的模糊评判模型,其中,指标权重的确定方法采用主观和客观赋权相结合,避免了单独采用主观法或客观法的片面性,实现了主观判断与客观评价的统一,使评价更加客观、真实、有效。并对一实例进行了预测分析,结果表明所提出的模型合理、切实可行。
In the traditional fuzzy evaluation model,the weights of indexes are determined by subjective or objective method alone.A comprehensive fuzzy evaluation model is proposed to forecast frost heaving.In the model,weights of indexes are determined by combinative method,which makes the model more realistic and more effective.The model is proved to be reasonable and feasible by comparing the calculation value and the test value of an example.
