Abstract
A method is introduced to evaluate the stability of high-cutting regional slope, and this method is suitable for the highway that is in operation. Taking the high slope along Huo highway in SanMenXia section for example, through field investigation and analysis of the existing geological data, a kind of index system that uses fuzzy comprehensive evaluates the stability of regional high slope and considers geological structure characteristics U1, landform U2, protective measures U3, and other influence factors U4 was confirmed. The analytical hierarchy process was used to determine the evaluation index weights of the index system, according to the method secondary fuzzy comprehensive evaluation and the principle of maximum membership degree, a model for fuzzy comprehensive evaluation for the stability of high-cutting regional slope was established.
