摘要
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。
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.
