In order to analyze the influence of soil frost heave on anchor anchorage of foundation pit and slope, and to determine more effective anchorage form. In this paper, the finite element method combined with the theory of segregation potential in frozen soil mechanics is used to simulate the calculation model. The influence curve of the frost heave force under the anchor action is obtained and compared qualitatively with the frost free force and the actual working condition .The result shows that it is feasible to calculate the frost heaving force by using the cooling self expansion and the frozen soil constitutive relation, and the frost heave force calculation function is obtained. The axial force and displacement of the anchor under the action of the calculated results are greater than those of the normal force under the same conditions, and the difference between the bolt form and the anchor condition is very different. The simulation results of frost heave force accord with the law of frost heave, and the force of actual anchor bolt is lower than that under simulation. The bolt under the same anchoring force is easier to destroy, it is of guiding significance for anchoring engineering in permafrost and seasonally frozen soil areas. |
