摘要

结合南京地铁某盾构施工区间，对纵向地表沉降进行了理论分析，提出了盾构掘进对纵向地表的影响范围，总结了盾构推进不同阶段引起地表沉降量占总沉降量的百分比。针对引起地表沉降因素的复杂性和不稳定性，将纵向地表沉降视为随机过程，基于延迟差分方程建立模型进行动态预报，并与实测数据进行比较。结果表明，该方法具有较高的准确性。

Abstract

In accordance with the interval shield tunnel of Nanjing Metro

the longitudinal ground settlement is theoretically analyzed. The area of longitudinal ground settlement by shield driven in Nanjing Metro is firstly presented; and the percentages of different course are summed up. In view of the complexity and instability of the information of ground settlement

the longitudinal ground settlement is considered as a stochastic process. Based on the delayed difference equation

the model for dynamic prediction is proposed. The predicting results

compared with the monitoring data

indicate that the model has high accuracy.
