Discussion on Mathematical Correlation between Liquid Limit & Plastic Limit of Cohesive Soil in Shanghai
This article collects a large number of engineering cases in Shanghai,selects the measured data of liquid limit and plastic limit of cohesive soil obtained from geotechnical tests,and studies the relationship between liquid limit and plastic limit of cohesive soil with different properties.It is found that there is a significant mathematical correlation between the two.The article uses mathematical and statistical methods to fit and analyze the measured liquid limit and plastic limit data,and obtains an empirical formula for calculating the plastic limit value based on the measured liquid limit value.Through the engineering case of a high-rise building in Shanghai,the plastic limit value obtained by fitting the mathematical formula is basically consistent with the measured value,which proves the reliability of the formula and can verify the accuracy of the plastic limit test results to a certain extent.It has certain practical value in engineering practice.In the future,this research direction is worth further expansion and analysis in conjunction with big data technology.
