| 摘 要： | 结合具体工程地质条件，在FLAC 3D程序中设置相应参数，对由于岩体蠕变引起的锚索预应力损失进行数值模拟，通过对比发现，考虑锚索预应力变化和边坡蠕变的耦合作用而建立模型并推导的变化公式，计算结果与实际工程测算结果相近，因此该数值模拟程序可为工程实践提供参考。

| Abstract: | In this paper,the prestress loss because of creep which in the specific engineering geological condition was simulated in FLAC3D program,and then the conclusion of numerical simulation was compared with the result which was calculated by theoretical function,the theoretical function of long-term prestress variation is put forward by the way which based on coupling of long-term prestress loss of anchor tie and slope creep,and builting a new mode. Then we found that the result between the two is close,therefo... |
