摘要
大规模城市建设诱发的工程性地面沉降已成为上海软土地区地面沉降新的制约因素。本文针对上海地区工程性地面沉降特点,运用灰色理论建立了非等时距GM(1,1)预测模型,并用工程实测数据进行检验,得到令人满意的预测结果。研究结果对预测和控制软土地区由建筑物群引起的地面沉降具有重要意义。
The ground settlement caused by large - scale urban construction has become a new restriction factor of ground settlement in soft soil area of Shanghai. An unequal time - interval GM （1,1） predicting grey model is established according to the characteristics of ground settlement in soft soil area. The model is proved to be satisfying through the examination of engineering practice, and is of significant importance for the prediction and control of ground settlement, induced by engineering construction.
