摘要
本文用灰色系统理论的非等间隔模型GM(1,1)对西安市朱雀大厦周边建筑物及地表沉降观测数据进行了建模、分析和预测,并且与传统的回归模型拟合结果进行了比较,比较的结果验证了该灰色模型在建筑物及地表沉降变形分析中的实用性、正确性和有效性。
Based on the settlement data from earth's surface and buildings around Zhu-Que building in Xi'an city, an unequal interval GM (1,1) in gray system is erected to model, analyze and forecast the data in this paper. And then the authors compare this model with the polynomial regression model. The result verifies the correctness, practicability and validity of GM (1,1) in analyzing settlement deformation of high building and surface.
