摘　　要：采用相似材料模型试验对相同EPS颗粒含量不同土灰比二灰土以及相同土灰比不同EPS掺量二灰土通过无侧限抗压试验和直剪实验对其强度性质进行了研究。结果表明:EPS颗粒二灰土试样与纯二灰土试样无侧限抗压强度接近。EPS颗粒混合轻质土的粘聚力随EPS颗粒掺入量和土灰比的增大而减小,但是当土灰比和EPS掺量较小时,对轻质土抗剪性能影响不大。The similar material model test was used to study the strength properties of lime fly ash soil with the same EPS particle content and different soil cement ratio,lime fly ash soil with the same soil cement ratio and different EPS content through unconfined compression test and direct shear test.The results show that the unconfined compressive strength of EPS granular lime soil is close to that of pure lime soil.The cohesion of light soil mixed with EPS particles decreases with the increase of EPS particles and soil cement ratio,but when the soil cement ratio and EPS content are small,it has little effect on the shear resistance of light soil.
