【摘要】 基坑边坡系统是一典型的灰色系统。其变形发展过程可用灰色系统理论进行预测。本文在常规全息GM(1,1)模型的基础上,采用等雏新息透代法GM(1,1)模型对郑州太阳城紫荆花因基坑变形进行模拟预测,结果表明了迭代法GM(1,1)模型比常规的GM(1,1)模型预测精度高,更符合工程实际。更多还原

【Abstract】 Pit slope is a grey system. Its deformation process can be predicted by Grey Model. In this paper, the ordinary GM(1,1) , Equal dimension new information and Iterative GM(1,1) are used to simulate and predict deformation of the new building pit in Zhengzhou city. The results show that precision of iterative GM(1,1) is better than ordinary GM(1, 1). The equal dimension new information iterative GM(1,1) is more applicable for engineering projects.更多还原
