Abstract
This thesis comprehensively analyzed the diseases on small-radius curved sections and the disease reasons, and proposed targeted treatment and prevention measures so as to ensure that the small-radius curved sections could be with good technical condition and balanced quality. Meanwhile, the statistical analysis of the disease status of the DK0-DK256 small-radius curved sections of the Shuo-Huang heavy haul railway was carried out, including the damages on steel rails, the deviations of track’s geometrical sizes, and the failures of joint accessories. Further on, the thesis discussed the specific reasons causing these diseases on the small radius curved sections and, in combination with field gropes and practices, proposed a series of effective maintenance and treatment measures for small radius curved sections. As a result, the use of the comprehensive maintenance and treatment measures in small radius curved sections has achieved good effect, which can extend the maintenance interval, reduce maintenance cost, and provide reference experience for the treatments of similar diseases.关键词
