Tests on anti-slide behavior of one soft soil bank improved by deep-mixing-cement pile(DMCP) is introduced.

Typical reinforcing and managing method of soft soil bank of Changjiang River levee project;

Therefore,based on the Boussinesq s differential equation of unsteady phreatic water movement and according to certain assumed conditions and utilizing the Laplace positive and inverse variations,this paper achieves the simplified predictive formula of the saturation line of the soil bank slope influenced by rainfall .

According to the study on the highway soil bank slope in the areas of Three Gorges,through the influential effect analysis of the action of reservoir water,the parameter and index assessment system and the corresponding grading standards of bank slope stability analysis are established.

Typical soil bank slopes of Three Gorges Reservoir area are taken as research object.

Damage from bank soil deformation to high-pile wharf;

The stability of soft soil slope is an engineering problem.

However, the mechanism of soil nailing for soft soil slope wasn t understanded completely, it s design theory lagged behind the engineering practice.

From the practice of the "slope soft soil"problem encountered duringThe railway construction in southwest mountainous area,in this paper,the cause analysis and engineering featurehad been studied by the test and engineering practice,and,the treatment measures of the embankment engineeringin the area of "slope soft-soil" has also been introduced.
