摘　　要：建筑物变形主要有沉降、倾斜、裂缝3种,其中建筑物不均匀沉降不仅对建筑物损害最大,而且也是诱发倾斜、裂缝等变形的主要因素,因此对于建筑物各部分的沉降预测是非常重要的工作。以某幢高层建筑物近两年的沉降监测成果为例,分别采用对数曲线回归与灰色系统方法对该高层建筑物进行沉降预测分析。分析表明,对数曲线回归与灰色系统都较好地拟合了该高层建筑物近两年的沉降情况,在两种方法的预测分析下该高层建筑物在未来将近一年内的沉降情况处于稳定阶段,其中该高层建筑物基于灰色系统的沉降预测效果要优于基于对数曲线回归的沉降预测效果。The deformation of buildings is mainly settlement,inclination and cracks.Among them,uneven settlement is not only the most harmful to the building,but also is the main factor leading to the deformation such as inclination and crack.Therefore,the settlement prediction of each part of buildings is very important.In this paper,the settlement monitoring results of a high-rise building in recent two years are taken as an example,and the logarithmic curve regression and grey system methods are used to forecast and analyze the settlement of the high-rise building respectively.The analysis shows that both logarithmic curve regression and grey system fit the settlement of the high-rise building well in recent two years.Based on the prediction of the two methods,the settlement of the high-rise building will be stable in the next year,in which the settlement prediction effect of the high-rise building based on grey system is better than that based on logarithmic curve regression.
