Large-radian overflow surface complex structure reinforced concrete bridge and dismantling method
The invention belongs to the technical field of bridges, and particularly relates to a large-radian overflow surface complex structure reinforced concrete bridge and a dismantling method. The method comprises the steps of: support designing and machining, support installing, arch rib and wind brace dismantling, bridge deck dismantling, middle span main beam and cross beam dismantling and side span main beam and cross beam dismantling, wherein the support designing and processing step comprises support designing and support processing. The dismantling construction method is suitable for any terrains, operation can be carried out under the conditions that the terrains are complex and large-scale construction machines cannot enter a site for construction, according to existing construction conditions, computer finite element software is used for designing a support form, and stress analysis is calculated. Compared with traditional construction methods, the method is low in cost and safe, the construction period is easy to guarantee, and the construction process of the construction method has small pollution influence on the environment and has creativity.
本发明属于桥梁技术领域，具体为一种大弧度溢流面复杂结构钢筋混凝土桥梁及拆除方法，包括支架设计加工、支架安装、拱肋及风撑拆除、桥面板拆除、中间跨主梁及横梁拆除、边跨主梁及横梁拆除，所述支架设计加工步骤包括支架设计和支架加工；本发明提出的拆除工法适用于任何地形，且能在地形复杂、大型施工机械无法进场施工的条件下展开作业，根据现有的施工条件，利用计算机有限元软件设计支架形式，并计算受力分析，该较以往的传统的施工方法成本低、安全、易保证施工工期，且该工法施工过程对环境污染影响小，具有创造性。
