Abstract:Loess cave developedin the loess plateau is a kind of unfavorable geo-hazard, and it has become the main
reason causing damage to the high ay in estern loess region.The formation of loess caves is not only relevant to
the engineering characteristics of loess itself such as collapsibility, disintegrative etc, but to many other geologic
factors such as geological structure, joint fissure, microtopography, hydrographic and climatic condition.
Moreover, engineering quantities and human activities along high ays are the influencing factors in loess area.
Therefore the evaluation of development density zoning of loess caves is complex, random and fuzzy.Based on the
distinct analysis of all the influencing factors, this paper studies the problem by fuzzy evaluation method.It is
found that the evaluation result is reasonable and reliable by comparing ith practical situation, so it can be
applied to the prevention of cave hazards in loess area.
