Embodiment Construction
[0022] The specific embodiments of the present invention are described below to facilitate those skilled in the art to understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes Such changes are obvious within the spirit and scope of the present invention as defined and determined by the appended claims, and all inventions and creations utilizing the inventive concept are within the scope of protection.
[0023] like figure 1 As shown, the evaluation method for evaluating the compaction quality of railway subgrade provided by this scheme includes the following steps:
[0024] S1: The road surface rolled on the railway subgrade is divided into several detection areas, and the length of each detection area is h , with a width of l , h The maximum width rolled by the vibratory roller ，l It is twice the circumference of the drum ...

The invention discloses an evaluation method for evaluating the compaction quality of railway subgrades, which comprises the following steps: dividing the road surface rolled by railway subgrades into several detection areas, collecting vibration compaction process parameters of a vibratory road roller, and dividing each detection area into The collected vibration compaction process parameters are loaded into different folders, the compaction degree of the detection point is detected, and input to the server to determine whether the compaction quality of all detection areas meets the requirements, and the GIS map will meet the requirements. Detection areas are marked in green and non-compliant detection areas are marked in red. This solution can quickly and extensively test the compaction quality of railway subgrades, and can more comprehensively control the subgrade compaction quality, while greatly improving the detection efficiency and reducing the construction period occupied by the detection.
Description
technical field [0001] The invention relates to the technical field of railway engineering, in particular to a method for evaluating the compaction quality of railway roadbeds. Background technique [0002] The roadbed is the foundation of the railway and is related to the safe and efficient operation of the railway. The subgrade is the foundation of the track structure. With the increase of train running speed, especially the application of high-speed railway, the subgrade structure is required to provide a smoother and more stable support for the superstructure. The compaction quality of the roadbed filling project is the foundation of its structural performance. The compaction quality of the roadbed includes three aspects: the degree of compaction, the uniformity of compaction and the stability of compaction. The degree of compaction is the rolling compaction of the roadbed. degree. At present, for the inspection and control of the compaction quality of roadbed filling ...
