Test Research of Dynamic Strength and Deformation on Geogrid Reinforced Cohesive Soil Under Cyclic Loading
The results of dynamic triaxial test of reinforced geogrid cohesive soil under cyclic loading indicate that the dynamic strength of reinforced cohesive soil shows good regularity with the change of amplitude of dynamic stress and number of reinforced geogrid layer. The forms of dynamic strength curve of reinforced cohesive soil are basically uniform with different conditions, and the dynamic strength curve can be expressed as τd = A Ln (-B Ln Nf). The axial cumulative strain increases quickly with vibration times increasing under cyclic loading during the earlier stage of the vibration which can reach 60% ~ 70% of the total strain. It remains stable with vibration times increasing if the dynamic stress is smaller than the limited dynamic stress. However, the axial cumulative strain increases slower than the axial cumulative strain during the earlier stage, and the curve of the axial cumulative strain is totally nonlinear if the dynamic stress is bigger than the limited dynamic stress. The sample eventually fails for instability. The development of the axial cumulative strain of reinforced cohesive soil shows good regularity along with the change of amplitude of dynamic stress and number of geogrid layers. The cumulative strain may be described as εp = A + B N C.
