摘要
鉴于深基坑变形监测具有影响因素的不确定性、灰色性等特征,利用灰色系统理论方法对基坑的变形发展趋势进行预测具有重要的实际应用价值。考虑昆明软土地区深基坑工程变形特点,建立深基坑监测变形的灰色系统GM(1,1)预测模型,并进行了工程实例分析。研究表明,此方法客观准确、操作简便,具有一定的实际应用价值,可为相关工程提供参考借鉴。
Due to the influencing factor of deep foundation pit deformation has uncertainty and grey characteristics, and using grey system theory method to forecast the development trend of foundation pit deformation has an important practical application value.Considering the characteristics of deep foundation en^neering in soft soil area, it establishes GM （l, l） prediction model of deep foundation pit monitoring deformation which based on grey system, and makes an example analysis. Results show： this method is objective and precise, easy to operate, and has certain practical applicationvalue, canprovidc a reference for relatedprojects.
