Attewell方法沉降预测在盾构施工中的应用

Application of Attewell Method on Settlement Prediction in Shield Construction

本文以广州市轨道交通三号线（沥漂站～大石站区间）盾构工程为背景，基于Attewell方法建立计算机模型，对盾构隧道掘进施工中引起的土体沉降进行预测，并利用施工中实测的沉降值对施工进行反馈，得出了有益的结论。

Based on Line 3 of Guangzhou rail transit line （Lijiao station-BoulderStation） shield as the background, the article uses Attewell method to establish the computer model, and predict excavation of shield tunnel construction soil settlement. By using actual measurement settlement values for the construc- tion of feedback, it draws useful conclusions.
