摘要

关于岩石蠕变特性的研究已有诸多成果，但对胶结充填体的蠕变特性还缺乏系统地研究。在室内充填体单轴蠕变试验的基础上，利用Hoek-Kelvin模型表征充填体的蠕变特性，运用粒子群优化算法，对选用的蠕变模型的参数进行辨识，并研究各蠕变参数对应力水平的敏感程度。研究结果表明，在不同分级应力水平加载下，弹性模量EH和黏滞系数η变化较小，而参数EK对应力水平变化较敏感。利用FLAC3D软件二次开发所建立的蠕变模型，用开发的模型进行分级加载蠕变的数值模拟，计算结果与试验数据吻合。

Abstract

Great many results about the creep properties of rock have been achieved

while few reports on the cemented backfill’ s creep characters were obtained. In this paper

creep property of cemented backfill is characterized by Hoek-Kelvin model. Cemented backfill creep experiments are firstly conducted in the laboratory

then the parameters of Hoek-Kelvin creep model are identified using particle swarm optimization algorithm. Meanwhile

the sensitivity of creep parameters to the stress level is studied. Results show that the numerical value of EH and η vary little at different loading stress levels

and EK is very sensitive to the change of loading stress level. The proposed creep model for backfill is developed with the software FLAC3D; and it has been used to numerically simulate multi-stage loading on cemented backfill. The numerical results agree well with the experimental ones.
