| 摘 要： | 新紫洞大桥主桥为83m＋150m＋83m的连续刚构，而主墩较矮只有13．5m高。施工方案为：合拢中跨前利用千斤顶在每个腹板形心处向边跨方向顶推1500kN的力，顶推时对称逐级加载，每级加500kN，以实现矮墩的合理内力和变位，同时也保证各主要施工阶段0^#块的受力不超出规范允许值。

| Abstract: | The principal bridge of Xinzidong Bridge is of 83 m 150 m 83 m continuous steel structures,while the main pier is short and only 13.5 m in height.Therefore,the construction plan is as follows: at the center of form of each web apply top pushing force of 1 500 kN towards side spans by means of jack before shutting central span,the top pushing force is loaded step by step,i.e.500 kN for each step,as to realize reasonable internal force and position variation of the short pier,and in the meantime ensure the stress on O" blocks in various principal construction phases is not over the value permitted by specification. |
