%X 因高速铁路对轨道的平顺性提出了更高的要求，而路基作为铁路线路工程的一个重要组成部分，其稳定性也十分重要。基于铁路基础设备网格化管理理论，利用模糊逻辑推理方法，得出高速铁路路基沉降风险评估模型，对高速铁路路基沉降风险可能性进行定量化，将路基沉降位置定位在200 m之内，实现对高速铁路路基沉降风险的精细化管理。采用兰新高铁实际数据，对一个200 m网格1个月数据依照模型进行实例验证。<br>High-speed railways require a high degree of ride comfort. The subgrade as an important part of the railway line project, its stability is very important. Based on the grid management theory of railway infrastructure, this paper used the fuzzy logic reasoning method to obtain the evaluation model of high-speed railway subgrade settlement risk. In this paper, the possibility of settlement risk of high-speed railway subgrade was quantified, and the settlement position of roadbed is located within 200 meters, which can realize the fine management of high-speed railway subgrade settlement risk. Finally, this paper used the actual data of Lanxin high-speed rail, and a 200-meter grid monthly data to validate the example
