基于地理信息系统的高速铁路大型临时设施选址模型

A GIS-Based Site Selection Model for Large Temporary Facilities of High-Speed Railways

摘要:

大型临时设施选址对高速铁路施工建设起着至关重要的作用，其主要为建造高速铁路生产和提供预制梁。为针对性解决传统选址工作前期勘察综合成本大、选址结果主观倾向明显且难以量化评估等问题，系统地梳理了选址因素逻辑架构，构建了多层次选址指标体系，结合ArcGIS空间解析，建立高速铁路大型临时设施选址模型。结合山东省已建成的大型临时设施实际位置进行模型验证，得到模型准确度为90%，佐证了本文选址模型的可行性与科学性。可为后续类似设施选址提供理论依据，也有助于形成高速铁路大型临时设施选址新的工作范式。

Abstract:

The site selection of large temporary facilities plays a vital role in the construction of high-speed railways. They are mainly used to produce and provide prefabricated beams for the construction of high-speed railways. To address the limitations inherent in traditional site selection methods—specifically the high costs of preliminary surveys， excessive subjectivity， and a lack of quantifiable assessment criteria—this paper systematically identifies the logical framework of influencing factors， constructs a multi-level indicator system for site evaluation and， in combination with ArcGIS spatial analysis， develops a site selection model for large temporary facilities of high-speed railways construction. The model is verified using the locations of large temporary facilities that have been built in Shandong Province， and the model accuracy is found to be 90%， which confirms the feasibility and effectiveness of the proposed site selection model. This paper can provide a theoretical basis for the site selection of similar facilities in the future， and also help form a new working paradigm for the site selection of large temporary facilities for high-speed railways.
