中文摘要：

地质环境复杂程度评价方法主要采用定性评价方法或者经验方法来评判,其评价结果具有过多的主观性因素.而可拓评判的方法是从可拓集合理论出发,引入模糊数学中隶属度的概念,选取主要影响因素并进行量化,建立多指标性能参数的综合评判模型,应用一种定量的指标权重的确定方法,以定量的方式表示评价结果.应用实例结果表明,该方法可以使评价指标最优化的接近场地的实际地质情况,有效避免主观因素的影响,评价结果有更高的可信度,具有推广价值和良好的应用前景,并可为相关规范规程的修订提供参考依据.

英文摘要：

The grade of complex degree of geological environment is traditionally evaluated by the way of qualitative analysis or empirical method, so the evaluation result is always intluenced by the excessive factor of subjectivity. But the extenics evaluating method is derived from extertics, which can establish a synthetical evaluating model with many performance parameters and indexes. Extenics evaluating can show the result quantificationally. The extenics evaluating method can make the evaluating indicators optimally summarize the practical geological situation, which can effectively avoid the influence caused by the factor of subjectivity, therefore the evaluating achievements have higher reliability uaturally. Compared with previous empirical method the extenics evaluated results can basically reflect the actual grade of complex degree of geological environment, as well as the extenics evaluating method can be effectively used to settle the actual engineering problems. Therefore the extenics evaluating method is of great application prospect, the results may be served as reference for modification and compilation of related standards and codes.
