在运营铁路桥梁中,由于部分梁端道碴槽板与梁梗间发生顺裂情况,因此,为了保证道碴槽板有足够抗剪强度不致遭受损坏,故现行的《铁路桥梁检定规范》(简称《检规》)规定,对受弯构件,除计算中性轴处剪应力外,还应检算道碴槽板与梁梗相交处的剪应力,以求保证受弯构件的道碴槽板能与梁肋一起可靠地共同工 In the operation of railway bridges, due to the partial cleavage between the ballast tank slabs and the beam stems, the ballast tank slabs have sufficient shear strength so as not to be damaged. Therefore, the current “Railway Bridge Inspection Standards” (“ Inspection Regulations ”) stipulates that, in addition to calculating the shear stress on the neutral axis of bent members, the shear stress at the intersection of ballast tanks and beam stems shall also be checked in order to ensure that the ballast tank capacity of flexural members Together with the beam rib together reliably
