摘要
为保障施工过程的安全性,消除弹性变形及控制线形,混凝土连续梁桥悬臂浇筑施工前需进行挂篮静载试验。文章结合孟加拉国卡纳普里三桥的施工工程,对其挂篮静载试验采用的"预应力筋配合千斤顶模拟施加力"的方式进行介绍,结果表明该种方法简单、快捷、可靠,可供同类似工程参考。
To ensure construction safety and eliminate elastic deformation and control linear, the form travelers static test before cast-in-cantilever construction of the continuous beam bridge is necessray. This paper introduces the force simulation method of combing stressed tendon with jack in form travelers static test according to the construction of 3rd Karnafuli bridge in bangladesh. The results indicate that this method is simple, fast, reliable and available for the similar projects..
