The invention discloses a method for predicting ground settlement caused by soil bin soil entering and discharge through a soil pressure balance shield. The method comprises the following steps: according to tunneling data and ground settlement data of the shield at the initial tunneling stage, through deducing a relation between a shield tunneling parameter (N/v) and ground loss caused by shield soil discharge, inversely computing screw conveyor soil discharge efficiency eta and ground settlement trough width I; establishing a ground settlement prediction formula during the next tunneling of the shield; selecting a next tunneling parameter and substituting into the formula to compute, so that the prediction of a ground settlement value is realized. The method disclosed by the invention is simple and practical and good in adaptability; the relation between the soil bin soil entering and discharge and the ground settlement is established from a shield tunneling mechanism, so that ground settlement caused by the tunneling parameter can be accurately predicted, and excessive upheavals and settlement values are prevented from being generated on the ground.
