Flow through fissures in rock mass applies simultaneously the normal hydrostatic seepage pressure and the tangent hauling force (the dynamic seepage pressure) on fissure walls.

Flow in the fissures of rock mass applies simultaneously the normal hydrostatic seepage pressure and the tangent hauling force(dynamic seepage pressure) on fissure walls.

Based on long-term monitoring and analysis of internal horizontal displacement and seepage pressure,it shows that there is shallow slow deformation in slope Ⅰa nd Ⅱo f Hongshibao landslide,which is affected by rainfall;and the deformation is not obvious in deep layer.

, hydrostatic seepage pressure and hydrodynamic seepage pressure (seepage body force).

The characteristic of seepage through dam body and layers in Longtan roller compacted concrete dam(RCCD)is analyzed, the hydrostatic and hydrodynamic seepage pressures in RCCD and their effects on stress in the dam are also presented.

There are capillary pressure permeability,hydraulic pressure permeability,and ion permeability(or concentration difference) on the basis of driving forces of concrete permeability.

The problem that the osmotic pressure of the outwater wells in every pumping station is too high during the first water diversion experiment and later developments are emphatically discussed.

In the stress and stability analysis of dam and rock slope with Finite Element Method (FEM), face loads are usually used to act on one side of elements of the interface between dam and foundation and the structural planes for simulation of the osmotic pressure on the interface and the planes.
