在隧道工程建设中,需要对其进行规律的沉降监测。以沪昆高铁麻园里隧道的监测数据为例,介绍了灰色模型的基本理论,通过采用传统的GM(1,1)灰色模型和该进的GM(1,1)灰色模型两种方法对数据进行处理,对模型的预测效果进行了分析。结果表明,改进的GM(1,1)灰色模型具有较高的精度,在沉降预测中具有较高的应用价值。

In the process of tunnel construction,the tunnel is need for regular monitoring. Taking Ma yuanli tunnel of Hu- Kun High Speed Railway as an example,this paper introduces the basic theory of grey model by using the traditional GM( 1,1) grey model and improved GM( 1,1) grey model methods,and analysis prediction effect of two model. The results show that the accuracy of the improved GM( 1,1) grey model is higher than the accuracy of the traditional GM( 1,1) grey model,and the improved GM( 1,1) gre...
