石灰处治土初始弹性模量与回弹模量关系研究

The Initial Elasticity Modulus and the Modulus of Resilience of Lime Soil

通过室内三轴压缩试验与回弹模量试验,对石灰处治路基土的初始弹性模量与回弹模量进行试验研究.研究结果表明,石灰掺量对初始弹性模量与回弹模量有显著影响,随着石灰掺入比的增大,石灰处治土的两种模量均增大.对石灰处治土的回弹模量与初始弹性模量进行了非线性回归,建立了两者的经验关系方程,可以为初始弹性模量应用于石灰土路基工程设计提供参考.

Through indoor triaxial compression test and modulus of resilience test. With initial elasticity modulus and the modulus of resilience of lime improved subgrade soil are tested. The results showed that： Lime dosage on the in- itial elastic modulus and modulus of resilience. With the increase of the mixed with lime of lime treatment both mod- ulus are increased. And established fitting relationship with the initial elastic modulus and modulus of resilience. For the application of initial elastic modulus can be more accurate in engineering provides the basis.
