Analysis of tunnel induced settlement due to tunnel development with a help of TBM is given in current article. Surface settlement trough and settlement profile in longitudinal and transverse directions is shown below. A brief analysis of semi-empirical method of tunnel induced settlement calculation and determination of strains around excavation is given. Volume loss is given based on the in-situ observation.
