某桥梁静荷载试验研究

摘要

当空心板梁桥的荷载试验效率系数为0.4～0.7时，很难判定板与板之间的联系刚度。通过某空心板桥梁荷载试验，判定该桥的承载能力是否满足设计荷载要求；分析横向各板梁在不同荷载作用下的受力分配，并与理论值进行对比，以判定各板梁之间的横向联系刚度，避免因横向联系较弱引起单板受力状态。%It is difficult to determine contact stiffness between the plates when the efficiency coefficient was 0.4~0.7 showed by load test of hollow slab bridge. Through the hollow slab bridge load test,determined whether the bridge load bearing capacity met the design requirements or not;analyzed the force distribution of lateral plate girder under different load stress,and compared with the theoretical value,to determine the transverse contact stiffness between the plate and girder,in order to avoid causing single plank with strength due to the transverse connection was weak.
