查询词典 strain at

At present, all the P-Y curve methods recommended by the referring code demand using geotechnic parameters C_u (three-axle undrained shear strength) and ε_50(the strain value that is equal to a half of the difference stress in the undrained triaxial compressing test). Moreover, we must do the complex and expensive triaxial geotechnic experiment to get those two geotechnic parameters, so they restrain the P-Y curve method from using comprehensively.
