摘要
应用土工合成材料处理桥头过渡段路基是减小不均匀沉降的一种有效手段,但是现行设计方法存在一定的问题.为此对原设计方法的假设条件进行了适当的修正,并在弹性膜理论的基础上,考虑路基施工过程中不同层位的实际沉降变形,推导了土工合成材料竖向布筋间距的设计公式,并用于工程实践,得到了较好的效果.
It' s a effective method to utilize geosynthetic to minimize differential settlement at the bridge approach roadbed,but its vertical design method has some problem in criterion. This paper revised the hypothesis of the criterion' s method,and on the basis of elastomeric membrane theory, taking into account the actual settlement of backfills during construction,deduced a new design method,and used it in an actual project,acquiring a good effect.
