Problems solved by technology

Since the disease and abnormal state of the slope in the main structure of the subgrade and the auxiliary structure can be identified through external observation or detection, it is convenient to directly set up monitoring points to shoot and collect its data for evaluation, but the abnormal state data or disease of the subgrade bed of the subgrade It is often concealed, and the reliable and accurate evaluation basis of the subgrade bed cannot be effectively collected by direct or simple observation methods. Therefore, it is necessary to study a reasonable health status evaluation scheme for the concealment and structural complexity of the subgrade bed structure of the railway subgrade.

Abstract

The invention provides a ballasted railway bed health state unit evaluation method and system, and the method comprises the steps: dividing a roadbed bed of a target line according to the length of the line, and obtaining each effective bed evaluation unit; collecting ground penetrating radar data corresponding to all evaluation units as evaluation basic data; on the basis, calculating sub-evaluation indexes reflecting the bed state and the bed disease in the evaluation unit range according to a set strategy, and determining corresponding weights through the FAHP technology, and making a decision of a comprehensive evaluation index of the evaluation unit; and obtaining an analysis and evaluation conclusion according to the comprehensive evaluation index, and outputting the analysis and evaluation conclusion in combination with position information and priority association. By adopting the scheme, the health state evaluation of the subgrade bed is realized from various influence factors in a targeted manner, the hidden abnormal state of the subgrade bed can be seen by a user through parameter processing and calculation, the abnormal state of the subgrade bed in the construction or operation process can be found in time, and assistance is provided for targeted optimization and maintenance of the subgrade bed.

Description

technical field [0001] The invention relates to the technical field of track line reliability evaluation and maintenance, in particular to a method and system for unit evaluation of the health state of a ballasted railway foundation bed. Background technique [0002] High-speed rail routes have developed into one of the indispensable modes of travel in modern transportation. The railway subgrade is the foundation of the track structure and is a geotechnical structure built to meet the conditions of track laying and operation. The subgrade is usually composed of subgrade basic structure and auxiliary structure; among them, the main structure usually includes subgrade bed, slope and foundation, and subgrade structure is divided into drainage structure, protective structure and reinforcement structure. The health status of subgrade bed directly affects the operation safety of track routes sex. [0003] During the operation of railway lines, the safety of the roadbed is always ...
