CRTSⅢ型板式轨道层间离缝下门型筋合理布置研究
Reasonable arrange ment of door type steel of interlayer gap for CRTSⅢslab track
摘要
Abstract
As Chinese independent innovation of slab track structure,there wasnot related research on force of structure and door type steel of CRTSⅢ slab track with interlayer gap so far.In reference to the structure of CRTSⅢslab track,finite element beam -solid model was established.And influences on the force and connec-tion effect of door type steel caused by different position and length of interlayer gap under different loads were analyzed.The results show that interlayer gap that appeared in the plates’boundary has the biggest influence on the connection effect of door type steel under the common effect of train load and negative temperature gradient, concrete at both ends of the track plate broken.So the setting form of encrypting door type steels at both ends of the track plate was put forward in this paper.By comparison,the effect of the arrangement of encrypting steels is better in the condition of interlayer gap.关键词
