摘要
在GM(1,1)模型及灰色相对关联度分析的基础上,提出了灰色关联类比GM(1, 1)模型,并提出了用单宽涌水量对GM(1,1)模型中的等时间隔进行处理,用流量等效法对溶隙岩体中的溶隙和大裂隙进行等效处理的思路。最后利用该模型对某隧洞涌水量进行了预测,得出了比较符合实际的预测结果。
On the basis of GM ( 1,1 ) model and grey-relevant anylysis, a grey-relevant GM ( 1,1 ) model is put forward. The unit discharge is used to substitute for isochronal interval in GM ( 1,1 ) model and equivalent flow is used to deal with Karst fracture and large fracture. At last, discharge of tunnel is predicted with the model. The reasonable result is obtained.
