预应力锚索的锚固机理与锚固效应影响因素的数值仿真试验

Based on the Fast Lagrangian Analysis of Continua calculation program, this article considered the traditional anchorage system as cable-grout-surrounding rock of separated transformer from the law of the pre-stress anchor’s load transferring and anchorage mechanism. The various destructive forms of anchorage system and judging equations were established. The following anchoring effect influencing factors such as pre-stress, anchorage length, anchor cable rigidity, the property of rock and soil mass were simulated by the numerical method. At last, the broken process of anchorage system was dynamically simulated by pull-out test, and the obtained results were credible and more closely accurately compared with the existing conclusion. The reliable reference for the practical application of engineering were provided and the further studies were pointed out.
