摘　　要：在公路选线设计中,地质稳定性是决定公路路线走向的一个非常重要的因素,选线时应充分考虑地质的复杂性和多样性,尽量避开不良地质地段,减少路线穿越不良地质地段的里程。本文利用GIS强大的数据管理和空间分析功能,针对天山公路实际,引入信息量模型,开发了地质稳定性评价系统,从定量的角度为天山公路设计提供了有效的决策支持。In the study of optimal design in selecting ways, the geology stability is one of the important factors to decide the highway route alignment. The complexity and diversity of the geology shoule be considered while choosing route. It is generally accepted that bad geology district shoule be avoided and the mileage that route crosses bad geology district shoule be reduced. Based on powerful function of GIS in data management and spatial analyses, and information content model, the paper develops an evaluation system of the geology stability accoeding to the facts of Tianshan-Road. It offers powerful basis of decision making to the optimal design in selecting ways in Tianshan-Road from the angle of quantitative analysis.
