Evaluation of Shaozhuang-Shuangmiao water site Quaternary pore water and Cambro-Ordovician karstic water environmental quality status quo were based on single constituent comprehensive evaluation.

Research on rationality of pore-water pressure coefficient which is defined in saturated region indicats that pore-water pressure coefficient is ineffectual for calculating slope cosmictally stability under infiltration.

In the paper, the problems are quantitatively calculated about the pore-water pressure coefficient and diaphram wall aging stability analysis on the basis of the conception of negative pore-water pressure produced from capillary water, which is directive to engineering practices.

By analyzing the problem of hydrological 3D spatial dispersion in 3D finite differential numeric simulation of porous groundwater flow, as well as discontinuous spatial distribution and asymmetric thickness of porous aquiferous strata and partitive groundwater stratum, the paper presents the GIS-based technique of 3D spatial dispersion of porous aquiferous stratum system.

The Quaternary aquifer division and character analysis of plain in Huaihe River basin;
