In order to explore the long-term influence of the difference of load-reducing materials on the deformation and safety of lining, three kinds of load-reducing materials, EPS plate, low-pressure solid soil and rubber particle mixed soil, were selected. The high-pressure solid soil was used as the filling soil. The influence of creep of different load-reducing materials and high-pressure solid soil on the long-term performance of high-filled open-cut tunnel was analyzed by means of experiment and numerical simulation. The results show that the creep curves of the four materials
