Types and Distributions of Saline Soil in Xuwei of Lianyungang and Its Influence on the Engineering Constructions
Abstract:Analyses were made of contents of eight easily-dissolved salts, salinity, types and spatial distributions of the saline soil collected from Xuwei of Lianyungang. The re- sults indicate a typical chloride-reach saline soil in the studied area. Within 50m down into the soil, the types of the soil are basipetally hypersaline soil → high saline soil → medium saline soil. The salinity, contents of all dissolved salts and corrosibility of the soil all tend to decrease with the depth within a range shallower than 15m in the soil col- umn. The contents of all items of the dissolved salts are generally higher in the ground- water than in the soil samples from the drillhole, showing a strong corrosibility. All re- sults have indicated that the soil in the studied area has been apparently affected by salt fields and seawater-type of groundwater for a long time. By comparing with the criteria for evaluating the engineering corrosions, the higher content of chloride within the range shallower than 15m in the soil studied has reached up to a strong level of corroding the building reinforcing steel and pipelines, which should be paid more attention to the coastal engineering epnlnrntinns in the future.
