摘 要:在理论分析的基础之上,开展对预应力混凝土矮T斜梁桥的试验研究,其中包括单梁的静力性能研究以及成桥的静、动力性能试验研究。通过试验对矮T斜梁桥结构的各项力学性能指标进行测试与分析,并对偏载及中心加载情况下各支点反力的分布特性进行探讨。试验研究结果表明:预应力混凝土矮T斜梁桥是一种性能良好、易于施工、耐久性好的新型桥梁结构形式,可以广泛用于平原地区中、小跨径的公路桥梁中。An experiment study concerning prestressed concrete T-shaped skew bridge with low web was developed on the basis of theoretical analysis,including static performance of single beam,static and dynamical performance of the whole structure.Each mechanics performance factor concerning T-shaped skew bridge with low web was tested and analyzed through experiment,specific distribution characteristics about the reactions were discussed under the condition of deflected load and symmetrical load.The experimental results show that the prestressed concrete T-shaped skew bridge with low web is a new type bridge structure with perfect performance,easy construction and better durability and can be applied in middle or small span highway bridge in plane area.
