Experimental study on mechanical properties of artificial frozen soil in marine sedimentary soft clay

In the ground freezing,the mechanical properties of the soft clay have a remarkable change after it is frozen.The mechanical parameters of frozen soil in urban rail transit project are the basis of freezing wall design and tunnel excavation.In this paper,the uniaxial compressive strength and shear strength test of frozen soil of the ② ～ ⑤ layer marine sedimentary soft clay for the passway of tunnels in the line 1,Ningbo urban rail transit project are executed.The specific heat capacity,thermal c...
