摘要
基于灰色系统理论,应用其等时距GM(1,1)模型及改进的新陈代谢模型对沉降进行预测,通过与蕴藻浜特大桥一墩的沉降观测资料的对比分析,证明文中提出的工后沉降灰色理论预测方法,在工程实际中是可行的。
Based on Grey Theory, this paper predicts settlement with equal interval GM （1, 1 ） model and improved metabolism model. Through contrast analysis of settlement data of Yunzaobang Bridge Abutment, it is proved that the prediction method for post-construction settlement based on Grey theory is feasible in engineering practice.
