Приведен анализ причин, вызывающих деформацию породы вокруг тоннеля и смещения его контура при использовании щитовых проходческих комплексов. Описан характер формирования мульды оседания земной поверхности в продольном и поперечном направлении, форма мульды оседания в пространственной системе координат. Рассмотрены полуэмпирические методы определения осадки земной поверхности, горизонтальных смещений и деформаций породы на поверхности земли. Приведены данные о потерях объема грунта, полученные по натурным наблюдениям.

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.
