Experimental Study on the Mechanical Properties of Sandstone under the Action of Chemical Erosion and Freeze-Thaw Cycles
Figure 10
Fitting curves of elastic modulus of sandstone samples and number of freeze-thaw cycles under different chemical erosions: (a) the elastic modulus curves under a confining pressure of 3 MPa; (b) the elastic modulus curves under a confining pressure of 6 MPa. E is the elastic modulus of the samples subjected to m times freeze-thaw cycles under different chemical solution. R2 is the correlation coefficient.
