摘要：After a preliminary study on the swell-shrink characteristic of the red clay of somewhere in Chongqing under the effect of dry and wet circulation through the laboratory geotechnical experiment, in order to study the swell-shrink characteristic of the improved soil under the function of dry-wet circulation, two admixtures of lime and cement were added to the red clay. The results show that: Under the same load condition, the swell-shrink deformation of the modified red clay decreases gradually with the increase of the number of dry and wet circulation, and finally reach to a stable. Under the effect of the same dry and wet circulation, the swell-shrink deformation of the improved red clay decreases with the increase of vertical load. The conclusions have some reference value for the engineering construction of similar ground soil.
