The Optimization Calculation Method Study on Longitudinal Lattice Girder of the Spray Anchor Bracing System
As the structure component of the spray anchor bracing system, at present the structure calculation method of the longitudinal lattice girder use more simple beam, continuous beam. In order to further research the calculation theory and applicability of the longitudinal lattice girder structure, making the calculation method reflect the mechanical properties of the longitudinal lattice girder accurately, this paper through the use of ANSYS finite element numerical simulation method, and the improved method of Winkler, considering the impact of the tangential component of the anchor rod axial force, and considering the impact of excavation conditions of the deep foundation pit actual, compare the calculation results of the internal force of the longitudinal lattice girder, concluded the optimization calculation method of the longitudinal lattice girder and the applicability.
