[Abstract]:Culvert is a widely used underground building, which belongs to concealed engineering and is known as lifeline project in the world. Reinforced concrete box culvert is a kind of culvert in water conservancy engineering, and its structure design is very important. This paper introduces the theory of box culvert structure calculation by finite element method and summarizes the internal force calculation method used in ANSYS. In this paper, linear analysis of three-dimensional solid finite element model and simulation of two-dimensional beam element model are carried out for the diversion hidden culvert in Zijin Lake water diversion project with the aid of ANSYS, and nonlinear finite element analysis of reinforced concrete box culvert is carried out. The main research work is as follows: (1) the principle and analysis steps of ANSYS finite element method and the relevant technical theory of ANSYS used in box culvert structure analysis are introduced. (2) the method of ANSYS to solve the internal force of solid structure is summarized. Several methods for solving internal force of solid element model are verified and analyzed by a simple supported beam example. (3) Three-dimensional solid model of Zijin Lake water diversion hidden culvert is established by ANSYS software. The three-dimensional finite element model is calculated and analyzed under the condition of water and anhydrous, and the results of stress and deformation of box culvert under different working conditions are compared and analyzed, and the control condition is determined as anhydrous condition. Based on APDL language, the second development of ANSYS is carried out, the internal force is programmed to solve the batch command flow, and the stress results of anhydrous working condition are integrated. The internal forces of each part of the box culvert are calculated one by one. (4) the internal forces of the Zijin Lake box culvert under the control condition are calculated by using the structural mechanics method and the finite element method of the ANSYS beam element respectively. The results of internal forces obtained by these methods are compared and analyzed. According to the results of internal forces of the control section, the results of reinforcement are compared and analyzed. (5) according to the results of reinforcement, The finite element model of reinforced concrete box culvert is established and the nonlinear finite element analysis is carried out to verify the reliability of the reinforcement results.
