The experiment results and the finite element results are compared and analyzed, and the following conclusions are reached. The cooperation between the internal and external walls is outstanding. Among the six proposed models, A3, A4 and A5 present almost the same results, which satisfyingly coincide with the experiment results. The horizontal pressure is mainly resisted by the internal wall under tension during the whole loading process. Before the force P reaches Pu-in, the vertical friction force is carried by both the internal and external walls. When the force P reaches Pu-in, the internal wall at the area between the first external ring beam and the supports shows a sudden elastic-plastic buckling. After that, the external wall bears more and more vertical friction force, then it also shows an elastic-plastic buckling at the same area. Finally, the walls at this area are destroyed and the model loses the bearing capability. Author Address: School of Civil Engineering, Southeast University, SiPaiLou 2, Nanjing, China, 210096
