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.
