摘　　要：采用数值仿真试验的方法,对全长粘结式预应力锚索加固基坑的机理从单锚和群锚两个层面进行了研究,研究结果和已有成果相比表明结果较为可靠,从而说明模拟方法比较合理。最后给出使用数值方法的一点体会。By use of the method of numerical simulation, the reinforcing mechanism of full-length-bonding pre-stressed cable on pit foundation was studied from two aspects of single cable and group cables. The obtained results were credible compared with the existing conclusion, indicating that the simulation method is relatively reasonable. Finally some experiences of application of numerical method were given.
