紫山灰场粉煤灰作为一种冲填土 ,粒度细 ,似粉砂。通过本次灌浆试验及施工 ,发现了一种新型的灌浆“帷幕”形态———水平或近似水平状的、连续的、呈近似圆形的“薄素混凝土面” ,它说明在水平方向是可灌的 ,它可有效地扩大渗径 ,增大渗透坡降。最后分析了“薄素混凝土面”的成因 ,探讨了其灌浆机理 Purple Mountain Ashfield fly ash as a red flotation, fine grain size, like silt. Through this grouting test and construction, a new type of grouting “curtain” is found, which is horizontal or nearly horizontal, continuous and nearly circular “thin plain concrete surface”, which shows that in the horizontal direction is It can be infused, it can effectively expand the osmotic path, increase the penetration gradient. Finally, the cause of “thin prime concrete surface” is analyzed, and the grouting mechanism is discussed
