Research On Saline Soil Of Western Jilin Province

The province of Jilin western region distributes the saline soil of the big area, because of being subjected to the saline soil influence of bad engineering property, the native area highway the construction is quality disease by the saline soil land to harm over a long period of time of harass, the big scope of highway exists the road to face to sink to decline, the roadbed falls to sink etc. The highway disease harm for resolving the highway to be subjected to the problem that the saline soil endanger by the root, this text is to take a high grade highway as an example, inquiring into the chemistry,physics,mechanics property of the saline oil. The highway construction of the saline soil land for the prevention and cure to provided and can consult with the roadbed disease suggestion.Investigate through many times, open country characteristic and diseases that understood the saline soil harm; The region that passes the spot to harm the serious district and saline soils to distribute to the concentration to the highway disease carry on sample's collect, carrying on the indoor soil work to experiment the research, controlling the saline soil basic physics and chemistry,mechanics property; Pass to control the content of the main composition NaHCO3 inside the saline soil, study the saline soil property to be subjected to the salinity influence; Pass to control the saline soil relation with amount of water, experiment research the saline soil anti- shear strength and contain of amount of water; The end research lime property to experiment, studying various index signs variety that the dissimilarity contains the amount of ash.Study the result enunciation :(1)The main composition of soil of the saline soil is a NaHCO3, the alkalescency is stronger, the salinity is not high, can be called the Alkali soil or Suda the saline soil. The aqueous solution of the saline soil has the bigger alkalescency.(2)The soil of the saline soil belongs to the low liquid of the medium compressibility limit powder quality to glue the soil, the saline soil mineral content is mainly with quartz and long stone is lord, glue the soil mineral mainly is a the YIMENG layer, mix the layer or so in 50%.(3)Along with the increment of the salinity, the contractility of the saline soil strengthen, the anti- shears the trend that the strength increases after have reduce first;(4)Along with the increment with amount of water, the anti- shears of the soil let up obviously;(5)After joining the lime reformation, various engineering properties of the soil all get well the trend, passing the dissimilarity to add the amount of ash on trial to get superior add the amount of ash.
