二灰改良土动力特性试验研究

近10多年来，二灰改良土以其造价低、有利于环保、后期强度高等特点，已普遍用做路面的底基层和基层。通过对素土和不同比例的二灰土改良土进行动强度，动弹模试验，研究二灰含量对动力参数的影响，并列出了几种配比的试验结果供比较和参考。试验结果表明，二灰含量不宜大于40%，否则意义不大，且不经济。

Experiment research of lime-fly ash Soil’s dynamics characteristics

Nearly for more than ten years, lime-fly ash soil has generally made the road subbase and basic unit due to its low construction cost, advantageous to the environmental protection, the long-term higher strength characteristic. the dynamic triaxial tests for different mixing proportions of soil and lime-fly ash soils to study lime-fly ash soils content influence on the dynamic parameter; and several kinds of mixing proportions test results are given for comparison and reference. The test results indicate that the lime-fly ash soil contents of larger than 40%, is not suitable otherwise the significance is not big, and is uneconomical.
