With the construction of high dams with large reservoir in China

the stability problem of slopes lied under atomized rain are serious. Atomized rain usually lasts rather a long time with heavy precipitation

under which it is very difficult to maintain the slope stability. The strength reduction of geomaterial or the load increase under the slope is the mechanism which causes the slope failure. However

the coupling action is less considered. Based on the theoretical analysis

two suggestions are made

the infiltration boundary condition is redefined in seepage analysis; the conception that the matrix suction is not equal with negative pressure of unsaturated zone is formed during the process of stress and strain analysis; and the matrix suction involves in spacing ratio and saturation

etc. As an example

the coupling analysis of seepage and stress is performed with a hydraulic slope under atomized rain.
