摘要： 地铁隧道建设规模不断扩大，工程建设期间经常需要判定工后沉降是否稳定，其关系到后期设备安装等工期计划。工程实践中常采用理论公式法、经验推算预测法及数值分析等方法。根据某地铁明挖隧道实例，采用上述三种方法判断研究工后沉降稳定问题，为合理安排工程筹划提供参考。

Abstract: In the metro construction practice, it is often required to predict the post construction settlement magnitude during the construction. A stable post construction settlement is critical for the scheduling of the equipment installation and others. Three methods are often used: theoretical method; empirical method; and numerical analysis method. This paper presents the results of all three methods. A decision of whether a stable post construction settlement can be obtained was made based on three settlement prediction results.
