不同配合比二灰土最佳力学指标的试验研究

Experimental Study on Optimum Mechanical Indexes of Lime-flyash-soil Cushion with Different Mixing Ratio

复合路基由不同材料合成,而不同材料的配合比以及含水量变化将影响到此类路基的质量。采用室内抗剪强度试验,定量揭示了不同配合比及含水量对抗剪强度指标(c、φ)的影响,并对其机理进行了探讨,为灰土路基填筑配料的设计与施工提供参考依据。

Composite roadbed consists of different materials. The different material mixing ratio and the change of water content will influence the quality of such roadbed. Adopting indoor shear strength test, different mixing ratio and water content affected on shear strength indexes（ c. q~）are revealed quantitatively. The mechanism is studied, and it offers reference for the design and construction of the Lime-flyash-soil roadbed＇s filling ingredient.
