摘要 本文通过研究二灰碎石、石灰稳定土和二灰土三种不同的半刚性基层材料在不同的应变和频动条件下的动态模量。可以得出这三种半刚性基层在应力状态下,动态模量随加载频率的增大而增大,同时动态模量具有应力依赖性,即随着荷载的增大(轴向应变增大),动态模量减小的规律。 This paper studies the dynamic modulus of three different semi-rigid base materials (two ash gravel, lime improved soil and two lime soil) under different strain and frequency conditions. Under the same stress state, the dynamic modulus of these three semi-rigid base materials increases with the increase of loading frequency. At the same time, the dynamic modulus has stress dependence. As the load increases (the axial strain increases), the dynamic modulus of this material decreases.
