目前混凝土岔枕时有裂纹出现,原因基本由于螺栓的横向力及上拔力共同作用的结果,为提高螺栓与混凝土接触面积,采用螺旋钢筋作为主要保护措施,但效果一般,通过ANSYS分析,采用复合套管的方式能有效避免岔枕裂纹的产生。
At present, cracks occur in concrete sleepers due to the joint action of the lateral force and the pull-out force of the bolt. In order to improve the contact area between the bolt and the concrete, the spiral reinforcement is used as the main protection measure, but the effect is general. By ANSYS analysis, The way of compound bushing can effectively prevent the occurrence of bifurcation cracks.
