摘　　要：结合合肥地区的城市轨道交通工程实例的基础沉降实测资料,采用不同计算方法进行天然地基地下建筑基础沉降量预测计算,即基于三点法、Peck公式预测对合肥市肥东地区粘性土地基的沉降进行了研究。结果表明,实际情况下三点法预测的沉降量往往比Peck法预测的沉降量更具有参考性。文章可以为粘性土地基处理提供依据,为按照变形控制原则进行地基基础设计提供借鉴。Combined with the measured data of foundation settlement of urban rail transit project in Hefei area,different calculation methods are used to predict foundation settlement of natural foundation underground building.Based on the three-point method and Peck formula prediction,this paper studies the settlement of cohesive soil foundation in Feidong District,Hefei City.The results shows that the settlements predicted by three-point method are often more referential than those predicted by Peck method.The paper can provide a part of basis for cohesive soil foundation treatment and reference for foundation design according to deformation control principle.
