摘要
The artificial freezing method has been more and more widely used in tunnel construction for Suzhou subway(such as the soil reinforcement of by-pass and shield passing in and out of working pit construction).In this paper,the typical underground soil from Suzhou was employed to conduct the in-door study for compressive strength,elastic modulus and poisson’s ratio.By analyzing the data and the curves,the regular pattern that the compressive strength changes by the influence of temperature,water content,dry density was proposed.In addition,the values of elastic modulus and the model of possion’s ratio to temperature were summerized.In the last,the quantitative analysis and mechanism analysis were carried out.The study result will be helpful in determining the designing parameters of freezing method in the construction of Suzhou subway.
