Optimization Inversion of the Ground Stress Field of Bohai Sea and Its Adjacent Area
Research Journal of Applied Sciences, Engineering and Technology, 2013 An optimization inversion model of the ground stress field of Bohai Sea and its adjacent area is established by combining Hooke-Jeeves optimization algorithm and finite element method. The study area was simplified into two 2D sections, a shallow and a deep section, for optimization inversion analysis in consideration of the spatial distribution of the
