Some basic problems of rectifying settlement of mat foundation under a building setting on soft clay by drawing-out soils homontally are studied. The influence of width rati0 9,depth ratio￡as well as load eccentricity on base pressure and its regulars are expounded. A design method of rectifying settlement is suggested, and an engineering example is briefly introduced, which may be useful for design and working.
