In this paper, the stress and strain fields of lithosphere in Himalayan Western Syntaxis orogenic belt and its adjacent areas since 10Ma are investigated through using the 3-D finite-element simulation, and deformation and evolution process in former 2Ma are simulated with different rheological parameters and rheological structure. Studies on functions in simulation process of different viscosity parameters, constitutive relation and changes of initial curst thickness show below results:(1) When various viscoelastic models are adopted, the selection of the coefficient of viscosity in the Western Syntaxis area has important influence on the its uplifts and evolutions. The computational results show that the viscosity in the Western Syntaxis area should be smaller than 1023Pa·s;(2) When the elastic model is adopted in relatively rigid Tarim basin, obvious changes are induced to the stress and strain fields of the whole Western Syntaxis area;(3) The existence of mechanical property stable block doesn′t make the propagation of the stress field show obvious decoupling phenomenon.
