摘要
针对箱梁转运过程,依托虎门二桥,研究了宽幅预应力预制节段箱梁增加对拉钢绞线及普通抗裂钢筋后的位移及拉应力,并探讨了两种抗裂防变形措施的利与弊。
Based on the project of Humen 2nd Bridge, this paper studies the stress and displacement of the wide prestressed precast segmental concrete box girder in the process of transportation after adding pull-back steel strands and crack-resistant reinforcement. In addition, it analyzes the advantage and disadvantage of the two crack prevention and anti-deformation measures.
