摘　　要：预应力混凝土等截面简支箱梁,由于其易于施工、养护的特点,使其成为桥梁施工中主要选择的对象。由于简支箱梁构件的特殊性,在施工阶段要满足质量及安全性要求,在后期运营过程中为了保证桥梁结构构建的可靠度,需对其进行成品梁静力荷载试验,并对试验结果进行理论分析,将其理论受力效应和实际受力变形相比较,观测混凝土简支箱梁在静力荷载试验工况下一系列的荷载反应,评价其实际承载能力。Prestressed concrete cross section such as simply supported box girder as a kind of easy constructionand maintenance of bridge structures, become the main choice of bridge construction object, due to the particularityof simply supported box girder components, to meet the requirements of quality and safety in the constructionstage, in the later operation process in order to guarantee the reliability of bridge structure construction,must be on the finished product Liang Jingli load test, and carries on the theoretical analysis of the experimentalresults, the force effect compared with the actual stress deformation theory, and observation of concrete simplysupported box girder under the working condition of the static load test of a series of load response, evaluateits actual bearing capacity.

关 键 词：静力试验荷载 理论受力效应 荷载反应 实际承载能力
