Abstract: With the development of undergroud structures in Shanghai,the ground freezing method has been more and more widely used in the construction of appurtenant parts of tunnels(such as the soil reinforcement of passways and pump house of tunnels).Exploring frost-heaving behaviors of artificial freezing soil is a key technology and an important research about artificial freezing method for municipal underground space.After the frost-heaving tests,the relationship between frost-heaving and freeezing end temperature is studied.The frost-heaving ratio and the frost-heaving stress are in linear relation with the freeezing end temperature.The freezing temperature of soil is measured by freezing temperature tests,and the freezing temperature distribution field of the soil samples is established.The relationship between freezing front and time is further revealed.
