The Effect Of Water Quality On Properties Of Stabilized Soil

MBER stabilized soil has been widely used in the Loess Plateau,but in salt water areas and saline soil area the application of stabilized soil is still blank. To solve this problem,the research has analysis the influence of water quality on the stabilzed soil by experiment and calculation software research, and has gotten the following results:(1) Experimental research of effect of the water quality on compressive strength of stabilized soil.In view of the research blank of MBER Soil Stabilizerapplication in thecoastal area andsaltwater areas,using different NaCl concentrationto study on the regularity of unconfined compressive strength and elastic modulus.According to the test results,this paper has gotten the functional relationship of 7d and 28 d MBERstabilized soil compressive strength,the effect of water quality on the relationship of stress and strain of the stabilized soil,therelationship curve between elastic modulus and compressive strength.With increasing concentration of sodium chloride,when the sodium chloride concentration is less than 0.5%,unconfined compressive strength and modulus of elasticity increases; when sodium chloride concentrations higher than 0.5%, the unconfined compressive strength and elastic modulus decreased;Trend of unconfined compressive strength and elastic modulus as salinity changing is consistent,linear correlation exist between them; An appropriate concentration of sodium chloride solution significantly enhance the early strength of stabilized soil. Studies suggest that in the actual project it can be used in the construction of stabilized soilwhen concentration of sodium chloride in water is less than1%.(2)Experimental research on the effect of water quality on the splitting tensilestrength of New MBER Soil Stabilizer. To study the impact of water quality on the splitting tensile strength,using sodium different concentrations of chloride solutions, theresearch hasstudied the regularity of splitting tensile strength of MBER solidified soil.the research has obtained the relationship between splitting tensile strength of the stabilized soil and concentration of sodium chloride and the relationship between splitting tensile strength and unconfined compressive strengthunder conditions of the effect water quality.According to the results,7d splitting strength sodium chloride concentration was significantly affected with respect to 28 d stress,its strength decreases with increasing concentration of sodium chloride,and 28 d splitting strength is not obviousby sodium chloride concentration.O verall,splitting tensilestrength ofstabilized soil did not change significantlywith increasing the concentration of sodium chloride. and is basicallyunchanged.This shows that the influence of sodium chloride on splitting strength of the stabilized soil increases with curing time and gradually reduced.(3)Experimental research on the effect of water quality on mud properties. To study the impact of water quality on mud properties, using different concentrationssodium of chloride solutions,theresearch hasstudied the regularity of splitting tensile strength of mud with reinforcingby MBER.The results showed no significant change of salinity affecting the strength of the mud.(4) Stabilized soi road structure analysis and the impact of water quality on its properties. Through analysis road structure of stabilized soil road, found in the vehicle load condition,the maximum tensile stress occurs at the bottom of stabilized soil surface layer, and maximum compressive stress occurs on top of the stabilized soil surface layer near the tire;In saline soil area, when the salinity is lower than a threshold,we can appropriate reduce the thickness of stabilized soil pavement to achieve better economic benefits; when the salinity is higher than a threshold,we can appropriate Increase the thickness of stabilized soil pavement to make the road safer.(5)Finite element analysis of cellar. In order to study the effect of water quality of the stabilized soil on engineering components, using finite element analysis methodanalyzed the stress of full cellar and empty cellar, the research has obtained in empty cellar conditionsthe maximum tensile stress and the maximum compressive stress was greater than in full cellar conditions. So empty cellar was the most unfavorable conditions.This paper has analyzes the impact of water quality on the properties of MBER stabilized soil cellar: when the water salinity varies from 0-4.5%,based on laboratory experimental data and using ANSYS analysis the cellar force and deformation in empty cellar condition, the reserarchhas discovered that with increasing salinity of water quality, the stress of cellar did not change,while theStrain of cellar decreased and then increased,at the salinity of 0.5% strain is the minimum.
