Which kind of failure mode of foundation usually has continuous sliding surface( )
A. general shear failure
B. local shear failure
C. punching shear failure
D. uncertain
According to Darcy's law, the greater the hydraulic gradient of the same soil sample, the faster the penetration rate ( )
The advantage of the triaxial shear test is that it can control the drainage conditions and measure the change of pore water pressure of the soil sample during the shear process( )
When the soil reaches the limit equilibrium state, the location of shear failure surface must be on the maximum shear stress surface( )
