基于可拓方法的地下工程围岩评价研究

RESEARCH ON SURROUNDING ROCK EVALUATION OF UNDERGROUND ENGINEERING BASED ON EXTENSION METHOD

介绍了可拓方法的步骤,建立了地下工程围岩评价的物元模型。研究表明,将可拓学运用于围岩评价是合理可行的,能够较好地反映各因素对围岩稳定性的影响。用简单关联函数确定权重,避免了实际工作中主观因素的影响。

The extension method is introduced, and the matter-element model for evaluating surrounding rock stability of underground engineering is established. The research indicates that the extension method is reasonable and feasible in evaluating surrounding rock stability, and it can well reflect every evaluating factor's influence on surrounding rock stability. The factor weight is determined by using simple dependent function, and this can avoid the effect of subjective factor of human in practices.
