摘　　要：随着我国铁路的不断发展,重载运输技术不断创新,运输效率得到很大提高,但是这也给运输组织与列车操纵带来众多问题。本文论述了重载列车长大下坡道试闸目的,分析了试闸地点的选择和试闸时判断制动力的方法,以充分利用试闸数据进行运行分析,提出具体建议。其目的是从根本上消除事故隐患,深化源头治理、系统治理和综合治理,强化底线思维和红线意识,化解2万t列车系统性重大风险。With the continuous development of China′s railways and continuous innovations in heavy-duty transporta⁃tion technology,transportation efficiency has been greatly improved,but this also brings many problems to transporta⁃tion organization and train operation.This paper discussed the purpose of the brake test of the heavy-duty train on long and big ramps,analyzed the selection of the test gate location and the method of judging the braking force during the test gate,so as to make full use of the test data for operation analysis and put forward specific suggestions.Its pur⁃pose is to fundamentally eliminate hidden dangers of accidents,deepen source governance,system governance and comprehensive governance,strengthen bottom line thinking and red line awareness,and resolve major systemic risks of 20000-ton trains.
