压实粉煤灰具有良好的施工特性、土工性能和一定的龄期效应,具有较高的抗震液化强度和抗水平推力的刚度。压实系数0.90～0.95;允许承载力150～250kPa,抗震液化强度7度。适用工业、民用建筑地基、港区陆域填筑、路堤、路基、地貌改造、造田。每利用1t粉煤灰可节省如筑堤之类处理费5～10元,同时少毁农田取,保护环境资源。若按年利用粉煤灰100万t计算,则可节省处理费500～1000万元,节约农田53hm~2。
Compacted fly ash has good construction characteristics, geotechnical properties and a certain age effect, and has high seismic liquefaction strength and resistance to horizontal thrust stiffness. Compaction coefficient of 0.90 ~ 0.95; allowable bearing capacity of 150 ~ 250kPa, seismic liquefaction strength of 7 degrees. It is suitable for industrial and civil construction foundations, landfills in harbor areas, embankments, roadbeds, landform transformation, and field development. Each use of 1t of fly ash can save processing costs such as embankment 5 to 10 yuan, at the same time less destroyed farmland to protect environmental resources. If one year is calculated by using 1 million tons of fly ash, the processing fee can be reduced by 500 to 10 million yuan, and farmland can be saved by 53 hm 2 .
