To solve the problem that there is no early-warning technique for conflict management of irregular flight services,the matter element analysis in extension theory was used to build an early-warning model with 5 indices(anticipated delay time,margin of resources,affected passenger number,service ability and event status),each of which has 5 grades(normal,attensional,precautious,danger and crisis).

为解决不正常航班服务管理中无冲突预警的问题，用物元分析方法，建立了以预计延迟时间、运力资源富余度、滞留人数、现场服务能力和意外事件情况为特征指标，以安全、注意、警戒、危险和危机为分类等级的预警模型。鉴于冲突中各种因素相互影响，采用简单可拓关联函数确定模型中的评价权重，并以定量结果确定预警等级。实例验证表明，该模型可用于对服务环境状况的定性评价，或提供定量的预警信息

According to the relevant datums and field investigations, the paper makes No. 316 national highway in South region as research region to analyze the conditions of inoculating disasters and slope s transform destruction model and draws such conclusions:(1)Many factors such as terrain, geomorphic, lithosome and solum character, geologic structure, neotectonic movement, rainfall condition, groundwater trait, anthropokinetic and so on influence on the study region, which make the geological disasters occurred frequently and generate enormous hazards.(2)The geological disasters have such distribution characteristics: terrain and tectonic make geological disasters development of osculating correlated property, relative concentrate property, packet property, periodic property and so on.

本文首先在搜集相关资料和野外调查的基础上，以陕南316国道公路为重点研究区，全面分析了研究区域内地质灾害的孕灾条件与斜坡变形破坏模式，得到了以下认识：(1)研究路段地质灾害的发生发展主要受控于区内地形地貌、岩土体特性、地质构造与新构造运动、降雨条件、地下水特征及人类工程活动等因素：(2)研究路段发育滑坡、崩塌、泥石流和危险斜坡等四种地质灾害，具有如下的分布特征：地势与构造对地质灾害发育的密切相关性、相对集中性、群发性、周期性等；(3)研究路段斜坡地质灾害主要有六种变形破坏模式分别为：顺层滑动破坏、蠕滑—拉裂变形破坏、弯曲—拉裂—剪断破坏、旋转式滑移—拉裂破坏、楔形体滑动破坏、堆积层沿基岩面的滑动破坏模式，而且斜坡灾害的变形破坏往往是多种模式的组合。
