摘要

建筑材料作为山区铁路工程建设的必要资源之一，对山区铁路建设存在支持与约束的双重作用。为了节约山区铁路工程建设材料，促进山区铁路工程与材料资源协调发展，基于耦合协调模型与障碍诊断模型量化分析山区铁路工程与材料资源之间的协调关系并识别其主要障碍因子。首先，基于隧道、桥梁、路基和站场4个节材关键专业，分析山区铁路工程与材料资源之间的交互影响关系。其次，依据交互影响关系，构建山区铁路工程与材料资源协调发展评价指标体系。再次，引进相对熵进行组合赋权，通过耦合协调度模型量化分析山区铁路工程与材料资源之间的协调程度，并通过障碍诊断模型识别影响山区铁路工程与材料资源协调发展的主要障碍因子。最后，以某山区铁路工程某标段为例进行实例验证。结果表明，该标段山区铁路工程与材料资源处于“初级协调发展”状态，耦合协调度存在较大优化空间，可以重点从喷射混凝土类型、喷射混凝土喷射方式、围岩变形预留、隧道断面超挖、土石方挖填平衡、弃渣资源化利用、废弃混凝土资源化利用、天然砂石料开采以及机制砂使用等9个方面着手，改善山区铁路工程与材料资源的协调状态。研究成果为山区铁路工程与材料资源协调发展评价提供了评判依据，也为提升山区铁路工程与材料资源协调状态明确了改进重点。

Abstract

As one of the necessary resources for railway construction in mountainous areas, building materials play a dual role of support and restraint in mountain railway construction. In order to save materials for railway engineering construction in mountainous areas, and promote the coordinated development of railway engineering and material resources in mountainous areas. Based on the coupling coordination model and obstacle diagnosis model, the coordination relationship between mountain railway engineering and material resources was quantitatively analyzed, and the main obstacle factors were identified. Firstly, based on the four key disciplines of tunnel, bridge, subgrade and station, the interaction between railway engineering and material resources in mountainous areas was analyzed. Secondly, according to the interaction relationship, the evaluation index system of coordinated development of mountain railway engineering and material resources was constructed. Thirdly, the relative entropy was introduced for combination weighting, and the coordination degree between mountain railway engineering and material resources was quantitatively analyzed through the coupling coordination degree model. The main obstacle factors affecting the coordinated development of mountain railway engineering and material resources were identified by the obstacle diagnosis model. Taking a certain section of a mountain railway project as an example to verify, the results show that the mountain railway project and material resources in this section are in the “primary coordinated development” state, and there is a large optimization space for the coupling coordination degree. It can focus on 9 aspects such as type of shotcrete, shotcrete spraying method, surrounding rock deformation reservation, tunnel section overbreak, earth and rock excavation and filling balance, waste slag recycling, waste concrete recycling, natural sand and gravel material mining and machine-made sand using, to improve the coordination between railway projects in mountainous areas and material resources. The research results provide the evaluation basis for the coordinated development of mountain railway projects and material resources, and also clarify the improvement focus for improving the coordinated state of mountain railway engineering and material resources.
