地铁盾构施工引起的地表沉降预测研究

Prediction of Ground Subsidence Caused by Metro Shield Construction

摘要: 本文依托广州地铁广佛线在建地铁工程研究了盾构施工时地表横向、纵向沉降的规律；提出一种利用插值法、最小二乘法的预测模型，并将模型应用到信息系统实现对盾构施工时刀盘附近地表沉降的预测。
>Based on the Guangfo line subway project under construction of the Guangzhou subway, the article studies the rules of the shield construction of surface transverse and longitudinal settlement. It refers to a prediction model using interpolation method and least square method. And the model is applied to the information system as a prediction tool for shield construction site near the ground surface settlement.
