摘要：

At present, vertical prestress detection is almost blank during box-girders construction of civil engineering. In order to effectively detect the effective tension at box-girder construction process in civil engineering based on the theory of structural dynamics, scene detection means, the relationship of box-girder vertical prestressing tensile force and dynamic characteristics of the exsertion segment reinforced was established. Vertical prestress of part of the box beam segments of a three-span prestressed concrete continuous rigid frame was detected, the shortcomings of the current vertical prestressing tensile force was analyzed. The results show that: the proposed method is direct, effective and able to effectively monitor the vertical prestressing tensile force. The research has important theoretical and engineering applications for crack prevention of box-girders.
