摘要
准确预测大型场地在堆载预压过程中的沉降量,对工程场地设计和使用极其重要。结合上海梅山堆料场地的地基处理工程实例,利用灰色理论建立等时距GM(1,1)模型,对堆料场地地基沉降量进行预测,取得了较高的准确度;同时与单向压缩固结沉降计算法进行对比分析,结果表明,灰色模型预测值更接近实测数据。
To the design and operation of a large engineering,it is important to predict accurately the ground sedimentation during the heaping test on the spot. Through the even time interval GM （ 1,1 ） model, the authors predict the soft ground sedimentation in the project of Meishan ground in Shanghai City. In comparison with other method,the fuzzy prediction model is much closer to the measured actual data.
