山西某场区地面沉降的灰色理论分析

Grey theory analysis of land subsidence in a field in Shanxi

对山西某场区地面进行了长期监测,发现场地存在大范围的不均匀沉降,且沉降规律随时间变化不明显。借助灰色理论分析方法,构建多组预测场地沉降的时间序列模型,对地面沉降量进行了预测和检验,得到了较为准确的沉降预测模型。

Long-term monitoring has been carried out on the ground of a field in Shanxi,and it is found that there is a wide range of uneven settlement in the field,and the settlement law does not change significantly with time.With the aid of grey theory analysis method,a number of time series models for predicting site settlement were constructed,and the amount of land settlement was predicted and tested,and a more accurate settlement prediction model was obtained.
