摘要： 艰险山区环境条件极端恶劣、地质灾害频发，铁路沿线桥隧工程占比大，为提高桥隧工程技术接口管理水平，构建贝叶斯反馈修正云模型对桥隧技术接口悬挂威胁等级进行评估。首先，以铁路桥隧工程技术接口为基础，考虑不同参建方之间的接口共性问题和艰险山区铁路建设面临的一系列技术难题对接口悬挂的影响作用，从业主方因素、勘察设计方因素、承包方因素、与项目关联的其他因素、外界因素5个方面出发，构建了桥隧工程技术接口悬挂威胁等级评价指标体系，并利用IFAHP法进行赋权。然后，运用贝叶斯反馈修正原理构建了艰险山区铁路桥隧工程技术接口悬挂威胁等级评估模型。最后，以贡多顶隧道和奔中车站双线大桥桥隧工程技术接口为例，对其悬挂威胁等级进行评估，并借助MATLAB进行可视化分析。通过工程实例表明，该技术接口悬挂威胁综合等级为严重，其中勘察设计因素对桥隧技术接口的悬挂威胁程度最高。

Abstract: In hard and dangerous mountainous areas, the environmental conditions are extremely harsh and geological disasters occur frequently. The proportion of bridge and tunnel engineering along the railway is large. In order to improve the technical interface management level of bridge and tunnel engineering, a Bayesian feedback correction cloud model was constructed to evaluate the suspension threat level of the technical interfaces. Firstly, based on the technical interfaces of railway bridge-tunnel engineering and considering the impact of the common problems of the interface between different parties and a series of technical problems faced by the railway construction in difficult mountainous areas on the interface suspension, the evaluation index system of the suspension threat level of the technical interfaces was constructed from five aspects, including the owner’s factor, the survey and design party’s factor, the contractor’s factor, other factors related to the project and external factors. And the IFAHP method was used to assign weights. Then, an evaluation model of the suspension threat level of the technical interface of the railway bridge and tunnel engineering in the difficult mountainous area was constructed by using the Bayesian feedback correction principle. Finally, the bridge-tunnel engineering interface of Gongduoding tunnel and the double-track bridge of Benzhong Station was selected as the evaluation object, and its suspension threat level was evaluated and visually analyzed by using MATLAB. Through engineering examples, it is shown that the comprehensive level of suspension threat to the proposed technical interface is serious, with the highest degree of suspension threat from survey and design factors to the bridge tunnel technical interface.

Key words: tunnel engineering; bridge and tunnel technical interface; interface suspension; Bayesian feedback cloud model
