Research On Saline Soil Foundation Treatment In Bohai New Area

In Bohai new area of Cangzhou, There are some natural conditions such as great season’s temperature contrasts, high groundwater level, high clay content in soil, large and centralized precipitation, all above make saline soil forms.Based on the local status of material supplied, chlorine saline soil reinforced by inorganic binder for subgrade material was studied.In this paper, the geotechnical properties of chlorine saline soil was tested and analyzed in general, road foundation hazards and disposal measures made by halomorphic soil was also analyzed.Aimed at soil property in Bohai new area,chlorine saline soil was single or combine reinforced by lime, fly ash and other inorganic binder.Based on experimental studies in a variety soil compaction reinforcement.Through economic analysis in saline soil improvement to evaluate their impact on the project cost.Some specific requirements were put forward for the construction of saline soil improvement. Experimental study of chlorine saline soil reinforcement in Bohai new area was made, including unconfined compressive strength,California bearing ratio, limit salt content, frost resistance and so on in different stage.
