Ballastless track foundation bed frost boiling and mud pumping disease state judgment method

Abstract

The invention discloses a ballastless track foundation bed mud pumping disease state judgment method, which comprises the following steps of: for a ballastless track line suffered from mud pumping diseases, marking the positions of the mud pumping diseases on the line, and dividing disease grades; track state detection operation is carried out on the line through a high-speed comprehensive detection train, so that track state data with frost-pumping and mud-pumping disease positions, different frost-pumping and mud-pumping disease grades and low-grade frost-pumping and mud-pumping disease development trends are obtained; selecting the height of the track and the vertical acceleration data of the vehicle body, which are most influenced by the mud pumping damage, as training data; constructing a ballastless track frost boiling and mud pumping disease state discrimination network, and inputting the obtained training data in the database into the discrimination network for training and storing; and the track state data newly obtained by the comprehensive detection train is input into the obtained ballastless track frost pumping disease state judgment network, the frost pumping disease state on the track is judged, the treatment scheme is optimized, and the operation safety of the high-speed railway train is ensured.

Description

technical field [0001] The invention relates to the technical field of geotechnical engineering, in particular to a method for judging a disease state of a ballastless track foundation bed tumbling mud and mud, in particular to a method for judging a ballastless track foundation bed tumbling mud and oozing disease state based on high-speed comprehensive detection train data, It is suitable for judging the disease state (disease location, disease level and low-grade disease development trend) of the foundation bed of high-speed railway ballastless track, and provides scientific guidance for the treatment of the subsequent high-speed railway ballastless track foundation bed. . Background technique [0002] Mud churn is a common subgrade disease of high-speed railways in my country. It occurs in both ballasted and ballastless tracks. It is a chronic disease of high-speed railway subgrades for many years. Ballasted track is the traditional track structure of high-speed railway....
