摘要

针对城市立交桥中独柱墩曲线梁桥的由于支座设置不当引起的‘脱空’现象,给出了独柱墩支座对斜弯桥的整体受力特性的有限元分析,讨论了支座偏位对梁体受力性能的影响。以杭州上石立交桥为例进行了支座设置分析。结果表明:设置合适的独柱墩支座偏距,可以保证不出现较大的扭矩和横向力,同时可减小支座出现‘脱空’现象的可能性,从而使整个结构更加安全稳定。
As for the separation of the abutments from the pier due to their improper location on the piers in the curved single-pedestal pier bridges in the urban overpasss,a finite element analysis of the support abutments on the piers is performed in the present paper.Effects of the support abutment deviation with respect to the pier axis on the mechanical behavior of the bridge are discussed.As an example,Shangshi overpass in Hangzhou is conserdered,and the erection of support abutments is investigated.It is seen from numerical results.That the appropriate layout of the abutment can assure lower torque and transverse force,as well as the low possibility that the abutments are separated from the piers.
