  • With the development of underground structures in Shanghai,the ground freezing method is more and more widely used in tunnel construction(such as the soil reinforcement of the passway and pumping house of tunnels). Therefore,it becomes important to develop guidelines for appropriate applications of such technology in Shanghai.This paper presents results of the instantaneous uniaxial compressive strength,which is one of the important parameters for design of the frozen wall.Lab tests were conducted on sap green ~ grass-yellow silty clay and grass-yellow mealy sand which were often encountered in the tunnel passway construction in Shanghai.The relationship between the compressive strength and temperature of two kinds of frozen soils were obtained.Effects of the temperature and water contents on the relationship were also evaluated.
