The results of the study indicate:(1) the stress, strain and velocity fields as well as the uplift rates of the model are consistent essentially with those of the prototype in nature;(2) the major driving force for intraplate tectonic deformation in central-eastern Asia results mainly from the compression of the Indian plate;(3) the existence of the RSBs, such as those of Tarim, Alxa, Ordos and Sichuan basin, is one of the basic origins for the development of large-scale compressional basins and the table-like uplift of the Qinghai-Tibet plateau;(4) The netlike plastic-flow in the lower lithosphere is faster than the displacement in the upper layer, controlling the tectonic stress and deformation fields in the upper crust;(5) the weakness layer distributed discontinuously in the middle crust influences the level of difference between the stress directions in the lower lithosphere and those in the seismogenic layer.
