Abstract

Considering the influence of atmosphere action, field test of swelling force on expansive soil is carried out in Nanning Guangxi. The test sustains a whole rain season. The testing results show that swelling force is closely linked to the process of rainfall. The phenomenon, that long drought turns the rain, induces a sudden change of swelling force. But the persistence of rainfall brings different influence on vertical and horizontal swelling force. The results of field test can provide reference to optimize the engineering design.
