摘要：
Firstly, the analysis method of soil arching effect was improved based on H&R soil arching model by introducing the state parameter of soil element at arching crown or pile head and the surcharge load acting on embankment crest.The improved analysis method of soil arching effect not only considered the elastoplastic state of soil element at arching crown or pile head, but also ensured the equilibrium condition of embankment load.Then, the analysis method of tensioned membrane effect was improved by considering the skin friction of geosynthetic-soil, and the calculation method of pile efficacy of GRPS embankment was deduced.Finally, the presented method was verified with laboratory model tests data and numerical simulation results of the publication to investigate its validity.Results show that analytical solutions have good agreement with measured data and simulation results, and the presented method can provide theoretical guidance for engineering practice. © 2019, Editorial Board of Journal of Huazhong University of Science and Technology.
