Abstract Ground settlement caused by shield construction for metro tunnels should be given more attention in the field of rail transit. Based on a subway project under construction for the Guangzhou Metro, the rules of transverse and longitudinal ground settlement during shield construction are studied. A prediction model using the interpolation method and least square method based on the Peck formula is established. Prediction results of the model applied in an information system showed that ground settlement could be well predicted with this model on the premise of non-extremum of settlement, providing a reference for engineering practice and theoretical research．
Abstract：
Ground settlement caused by shield construction for metro tunnels should be given more attention in the field of rail transit. Based on a subway project under construction for the Guangzhou Metro, the rules of transverse and longitudinal ground settlement during shield construction are studied. A prediction model using the interpolation method and least square method based on the Peck formula is established. Prediction results of the model applied in an information system showed that ground settlement could be well predicted with this model on the premise of non-extremum of settlement, providing a reference for engineering practice and theoretical research．
