| 摘 要： | CFG桩复合地基的工后沉降受到多种不确定因素的影响。本文根据灰色系统理论的处理方法,分别采用普通GM(1,1)模型、新息GM(1,1)模型和新陈代谢GM(1,1)模型,对采用CFG桩进行地基处理的某建筑物地基沉降进行了预测。结果表明:新陈代谢GM(1,1)模型由于淘汰掉旧的沉降数据、加入新的沉降数据,所以能够更准确地模拟CFG桩复合地基沉降的真实情况。

| Abstract: | The settlement of CFG-pile composite ground is affected by many uncertain factors.According to the method of grey system theory,ordinary GM(1,1) model,renewed GM(1,1) model and metabolic GM(1,1) model can be used to analyze the settlement of the construction respectively.The results show that,by washing out old data and admitting new data,metabolic GM(1,1) can simulate the settlement more accurately than the other two methods. |
