C: correction coefficient of bearing capacity of ground
D: uncertain

B: modified characteristic value of bearing capacity of ground
C: correction coefficient of bearing capacity of ground
D: uncertain
举一反三
- The characteristic value of bearing capacity of foundation is the bearing capacity of foundation considering both the foundation strength and the deformation.
- The study of the bearing capacity of ground is for reasonable foundation design.（ ）
- When foundation deformation is allowed and the ground is stable, the capacity to withstand the load per unit area is called the bearing capacity of ground.（ ）
- When calculating the bearing capacity of members under combined load of shear and torsion, the interaction relation between shear and torsion should be considered for concrete bearing capacity while the reinforcement bearing capacity is just the linear superposition of shear bearing capacity and torsional bearing capacity of reinforcement.
- Since concrete is a kind of elastoplastic materials, when calculating the torsional bearing capacity of plain concrete member, elastic analysis method should be adopted.
