试验研究结果表明 :淤泥掺粉煤灰后其力学性质指标有了显著的改善 ,而且泥灰浆液混合吹填的沉积土比搅拌配制的二者混合土具有更好的工程性质。根据试验结果计算得知 :泥灰比≤ 1的混合吹填地基加固比淤泥吹填地基加固能节省 80 %以上的预压时间或减少 80 %以上的砂井数目。

Results of experimental studies indicate that the engineering properties of silty mud are significantly improved after the silty mud is mixed with fly ash and that the deposit of silty mud fly ash slurry has better properties than the silty mud and fly ash mixture made from proportioned mixing. It is known from the experimental studies that, to improve the hydraulic fill of silty mud and fly ash slurry with a mix proportion of mud and fly ash of≤1, the time for preloading can be cut by more than 80%,or the number of sand drains can be reduced by more than 80%.
