Dynamic Characteristics Study of Geosynthetic-Reinforced Soil under Cyclic Loading
The technology of geosynthetic reinforced soil has been widely used in the structural strengthening of highway subgrade. It can improve the bearing and deformation resistance capacity of the subgrade effectively, prolong the service period of the road to ensure the safety and comfort of the vehicle. So far, the quasi-static method to design the geosynthetic reinforced subgrade under the action of traffic load is not perfect enough. The study on dynamic property, design theory and parameters lags far behind the application and improvement of the geosynthetic reinforced soil technology. This paper used the dynamic triaxial test in laboratory by taking different kinds of soil (clay and silt), different confining pressure (50kPa, 100kPa, and 150kPa) and different reinforcement layer (0 layer, 1 layer, and 2 layers) to study the change rule and influence factors of dynamic modulus of elasticity. This study would provide the gist for the improvement of dynamic design theory and parameter choice of geosynthetic reinforced subgrade with the effect of traffic load.
