摘要
运用高流态粉煤灰混合料填筑桥头引道路堤,是减小路桥衔接处的沉降差异、消除桥头跳车的有效方法。基于正交试验的高流态粉煤灰混合料配合比设计方法,不仅是一种切实可行的桥头引道路堤回填新方法,也能达到保护生态环境、减少资源浪费的目的,对于同类型高流态粉煤灰混合料工程的配合比设计具有一定的指导意义。
Using high-flow fly ash mixture to fill embankment at approach road of bridge is an effective method to reduce the settlement difference of the section where bridge and road linked,and eliminate the abutment jump.The article proposes a mix proportion design method of high-flow pattern fly ash mixture based on orthogonal test.It is not only a practical and feasible new method for embankment filling at approach road of bridge,but also can protect environment and reduce resource waste.It has a certain directive significance to the mix proportion design of similar high-flow pattern fly ash mixture.
