CONSOLIDATION BY VERTICAL DRAINS TAKING WELL RESISTANCE AND SMEAR INTO CONSIDERATION

摘要: ABSTRACT A rigorous solution for the consolidation of soil by displacement-type vertical drains with finite permeability is presented taking into account disturbance in a clay ring surrounding drain pile caused installation. The accuracy both Barron’s and Hansbo’s approximate solutions regarding well resistance smear examined detail comparing this solution. numerical results reveal that influence upon rate notably large type whose decreases disturbance. In case, existing are shown to be sufficiently accurate practical application. For compressibility increases disturbance, on other hand, relatively small. types, simple equations proposed obtain an equivalent “ideal” having increased spacing ratio basis analytical derived from
