摘要：

This paper presents the results of field plate loading tests and laboratory dynamic loading tests carried out to evaluate the performance of geocell where it is used to reinforce soft sub-grade for high-speed railroads. The factors selected in the tests include the type of infill material, the number of geocell mattress layers, the thickness of cover soil, the stiffness of the original foundation soil, and the presence of geotextile separating the geocell mattress and the neighboring foundation soil layer. The results of the tests confirmed the effect of geocell mattresses in improving load-bearing capacity of soft soil. The settlement rates of geocell reinforced railroad structure subjected repeated loadings were revealed from the dynamic loading tests.
