Through the field test in the construction of lime soil foundation with compaction pile composite foundation reinforced cushion, the stress on top of the pile and on the soil between the piles and the strain of the triaxial geogrids were tested, and the variation curves of pile-soil stress ratio and the strain of triaxial geogrid with construction height were obtained.It is shown that in the composite foundation with reinforced cushion and lime soil compaction pile under the strip foundation, the stress at the top of the pile and the soil stress between the piles vary in different positions;the variation trend for the soil between piles is different also, and the maximum value is reached at the center of the transition between the column and the strip foundation.With flexible displacement meter the deformation of geogrid was measured in terms of geogrid strain in the longitudinal, transverse and inclined process line.The test showed that the strain variation in different position of the geogrid is different, and reaches the maximum in the column and the center bar based handover.In the same position, the three different directions of strain change process lines are also different, and the maximum stress is at the center of the transfer column strip foundation under oblique ribs.
