Based on this,taking the Ziyangcheng landslide in reservoir area of the Three Gorges as an example,this paper uses the simplified formula of groundwater saturation line to analyze the dynamic stability and contrasts the result with that by the general evaluation method.

Effect of water-controlled partial wetting irrigation on the growth and water use efficiency of leaf lettuce;

Computational method for consolidation settlement considering submergence due to groundwater during preloading;

Analytic solutions for phreatic line in reservoir slope with inclined impervious bed under rainfall and reservoir water level fluctuation

The following problems have been studied:engineering classification of landslide;selection of parameters of slip surfaces;computation of seepage pressure;determination of phreatic line when water level declines;selection of calculation performance and the evaluation of landslide stability.

Under the long\|term action of flood,the phreatic line rises and reaches the toe of the landslide slope.
