Abstract:

The advantages of anchor frame lattice are overviewed and the three-dimensional finite element calculation model of anchor pier is established. Through the comparative study on finite element simulation and indoor experiment, mechanical mechanism, the development of deformation and fracture are explored. The efficiency of ANSYS software application in the design of pre-stressed concrete members is demonstrated.

Key words:high strength pre-stressed concrete lattice; three-dimensional finite element; fracture; anchorage; geological hazard control
