摘要
以日兰高速公路巨野西至菏泽段改扩建工程桥涵台背回填为工程应用背景,设计了配合比设计试验和现场试验,确定了液态粉煤灰施工最优配合比以及液态粉煤灰台背回填施工的技术指标。
Taking the backfilling of bridge and culvert abutment back of Juye West-Heze section reconstruction and expansion project of Rizhao-Lankao expressway as the engineering application background,the mix proportion design test and field test are designed in this paper.The optimal mix proportion of liquid fly ash construction and the technical indexes of liquid fly ash abutment backfill construction are determined.
