| Abstract: | The downward deflection of the Qinghai-Tibet lithosphere due to the topographical load is calculated with finite element method by use of the 3D multilayered shell structural unit.Then,the influence of the lower-velocity layer of thermokarst on the intensity of the Qinghai-Tibet lithosphere in different regions is studied with multilayered mechanical model,based on the seismic-wave velocity structural model and the constrained Moho model.The results show that the lower-velocity layer of thermokarst has a stronger influence on the lithosphere in the eastern region of the Qinghai-Tibet plateau than that in the western region. |

| Keywords: | Qinghai-Tibet plateau lithosphere FEM(Finte Element Method) flexure lower-velocity layer |
