N2 - The surface settlement curves observed from several deep excavation sites are very similar to the ones measured from the shield tunnel sites. Therefore, this paper presents an experiential formula based on the surface settlement curves of shield tunnel excavation to predict the one during a deep excavation. Four cases studies were adopted to check the suitability of the formula to apply on predicting the settlement due to deep excavation. The predicting results indicate that not only the maximum settlement, differential settlement but also the angular distortion correlate the data obtained from the sites well.
