The embodiment of the invention provides a method for maintaining the fixed capacity of a high-speed railway network diagram under abnormal events. Train delays are predicted with a GBRT model, an optimized model of a train delay operation substitute diagram based on operation adjustment is constructed, a feasible train operation diagram is generated, and the high-speed railway network capacity under the abnormal event is calculated; the road capacity is calculated from the generated train operation diagram after adjustment, a high-speed railway network capacity weight network under the abnormal events is established, and thus a high-speed railway capacity bottleneck road section is further distinguished; an OPENTRACK simulation software is utilized to simulate high-speed railway operationunder different delay conditions, the capacities of high-speed railway sections and stations under the abnormal events are analyzed, the calculation results are fed back as capacity constraints to analternative diagram optimization model based on operation adjustment, the high-speed railway network capabilities under the abnormal events are iteratively calculated, accurate estimation of the high-speed railway network capabilities is achieved, capacity retention strategies are generated, and macro-references are provided for high-speed railway dispatching and operation diagram adjustments.
Description
technical field [0001] The invention relates to the technical field of rail transit capacity analysis, in particular to a method for maintaining high-speed rail network map capacity under abnormal events. Background technique [0002] The occurrence of abnormal events always restricts the improvement of the capacity of the high-speed railway network. Different types of abnormal events will lead to different degrees of train delays. The energy imbalance will cause trouble to the running organization and operation plan of the high-speed train. Abnormal events are mainly divided into natural disasters, accident disasters, public health, and social security. Specifically, traffic accidents, fires, explosions, geological disasters, meteorological disasters, facility and equipment accidents and other events. [0003] In recent years, my country's high-speed railway construction has developed rapidly and has gradually become the main channel for passenger transportation in my cou...
