Study on Evaluation of Coordination Degree of Technical Interface Management Between Railway Bridge and Four Power Engineering in Difficult and Dangerous Mountainous Area

为提高艰险山区铁路桥梁与四电工程技术接口管理水平,使铁路工程建设高效有序进行,构建协同熵模型对艰险山区铁路桥梁与四电工程技术接口管理进行协同度分析。首先,以铁路桥梁与四电工程技术接口为基础,从技术属性、责任属性、时间属性和空间属性四个方面构建技术接口管理协同度评价指标体系,利用博弈论将改进的群体层次分析法和熵值法进行组合,并借助MATLAB计算各评价指标权重。然后,基于协同熵理论构建艰险山区铁路桥梁与四电工程技术接口管理协同度评价模型。最后,以绒乡雅鲁藏布江特大桥与四电工程为例,对其技术接口管理协同度进行评价。结果表明:所选研究对象技术接口管理水平整体处于基本协同状态,其中空间属性处于高度协同状态,技术属性处于良好协同状态,而责任属性处于极弱协同状态,时间属性处于弱协同状态,是技术接口管理重点关注的方面。

In order to improve the level of technical interface management between railway bridge and four power engineering in difficult and dangerous mountainous area,and make railway construction progress in an efficient and orderly manner,a collaborative entropy model was established to analyze the coordination degree of technical interface management between railway bridge and four power engineering in difficult and dangerous mountainous area.First of all,based on the technical interface between railway bridges and the four power engineering,the technical interface management synergy evaluation index system was constructed from four aspects of technical attributes,responsibility attributes,time attributes and spatial attributes,the improved group analytic hierarchy process and entropy method were combined by using game theory,and the weight of each evaluation index was calculated by using MATLAB.Then,based on the theory of synergy entropy,an evaluation model of coordination degree of technical interface management between railway bridge and four power engineering in difficult and dangerous mountainous area was constructed.Finally,taking the Rongxiang Yarlung Zangbo River Bridge and the four power engineering as an example,the coordination degree of technical interface management was evaluated.The results show that the technical interface management level of the selected research objects is in a basic collaborative state as a whole,in which the spatial attribute is in a high cooperative state,the technical attribute is in a good cooperative state,while the responsibility attribute is in a very weak cooperative state,and the time attribute is in a weak cooperative state,which should be paid attention to in the technical interface management.
