| Abstract: | The effective stress variation regularity is presented with the effective stress principle in the soft ground treatment on the road.Then,the mechanism of the ground strength increase and the principle of the soft soil compression deformation are discussed.Finally,the lateral deformation is analyzed with the stress path method.According to the mechanism of surcharge preloading in soft ground treatment,the measure effect of a soft ground treatment is introduced. |
