近年来,我国投入使用的高等级公路日益增加,随着行车速度的提高,“桥头跳车”已成为高速行车条件下的一个重大安全隐患。文章通过剖析“桥头跳车”产生的原因,提出了采用拌制的流态水泥粉煤灰混合料进行浇筑施工的方案,取得了良好的处置效果。
In recent years, the high-grade highways put into operation in our country have been increasing day by day. With the increase of driving speed, “bridge jumping” has become a major safety hazard under high-speed driving conditions. By analyzing the causes of “bridge head jumping vehicle”, the article put forward the plan of pouring construction using the flowable cement fly ash mixture and achieved a good disposal effect.
