Background The railway subgrade is an important basic structure of railway engineering, and the construction quality of the railway subgrade is directly related to the stability and operation safety of a line. Railway roadbeds are generally constructed in a layered filling and layered rolling mode, and construction quality control has obvious layering, stage and continuity characteristics. In the existing construction management, a great amount of quality related information is continuously formed in the roadbed construction process, and the compaction state, the geometric state, the bearing or deformation performance and the like are covered. The information sources are scattered and the formation time is different, and the information sources are usually stored in the form of test sheets, reports, machine accounts or independent files, so that the information sources are difficult to directly correspond to specific construction sections and filling layers, and when pressure compensation, retest or return occurs, relevant records are easy to be scattered and stored, and unified reference and tracing are inconvenient. On the other hand, the existing quality judgment is usually mainly based on single detection results or manual comprehensive judgment, and when the compaction indexes reach the standards and the bearing or deformation indexes do not meet the requirements, the lack of further auxiliary judgment rules easily causes unclear release basis, and even the situation that the problem of the previous layer is not treated and the construction of the next layer is continued occurs. In addition, the existing BIM application focuses on model display and general information management, and a layer-by-layer judgment and release control method matched with the railway roadbed layered filling process is not available.
