The present paper is concerned with the prediction for the maximum settlements of ground surface adjacent to open cut. Using many field measurements, statistical analysis were made for the maximum settlement and the distance from wall where more than 2mm settlement occured. It became clear that those values are influenced considerably by the following factors; (1) ground type, (2) cutting depth H and width B, (3) deformation modulus of soils under excavated base, and (4) wall type. The parametric study by the FEM have confirmed the significance of statistically analized results. And it is shown that maximum settlements are influenced by the proposed cutting factor (BH/βDD). D is the wall length under excavated base and βD is coefficient related to the wall stiffness and deformation modulus of soil.
