我国早期建造的整体现浇板梁,由于设计原因板梁横向配筋仅按构造钢筋配置,导致多数桥梁板底在运营过程中出现严重的纵向通长开裂。本文根据一座整体现浇板梁桥的静载试验,采用模型修正的方法对其承载能力进行评估,能够真实反映桥梁结构的承载能力状况。本文提出的模型修正方法对整体现浇板桥的承载能力评定具有一定的借鉴意义。
Because of the design reasons, the horizontal reinforcement of slabs and beams is only configured by reinforcing steel bars, leading to serious longitudinal long-length cracking in the operation of most bridge slabs. Based on the static load test of a cast-in-place concrete-filled girder bridge, this paper evaluates the bearing capacity of the cast-in-place girder bridge by using the method of model modification, which can truly reflect the carrying capacity of the bridge structure. The model correction method proposed in this paper has certain reference value for the assessment of bearing capacity of the whole cast-in-site slab bridge.
