| Abstract: | The resent studies had shown that the geological hazards such as the building subsidence,landslide and debris flow happened in PR China recently are mainly caused by the coupling effect of changes in groundwater table and vertical load.In order to understand the strength characteristics of the soil foundation,the experimental investigation has been conducted to simulate how the changes in water content and groundwater table fluctuation number will affect the shear strength characteristics(cohesion and frict... |
