| 1. | Finally, C . M . Anderson's research included more effective stress management techniques.
|
| 2. | The maximum past vertical effective stress is termed the " preconsolidation stress ".
|
| 3. | It is often used in the calculation of the effective stress in a soil.
|
| 4. | And the strength is very sensitive to the effective stress.
|
| 5. | "? "'= the effective stress friction angle, or the'angle of internal friction'after Coulomb friction.
|
| 6. | As the groundwater is pumped out, the effective stress changes, precipitating consolidation, which is non-reversible.
|
| 7. | If water is being withdrawn, the spheres are forced together and the effective stress increases.
|
| 8. | The concept of effective stress truly becomes interesting when dealing with non-hydrostatic pore water pressure.
|
| 9. | This weight and pressure is the effective stress.
|
| 10. | However, on reaching a state of zero effective stress such soils immediate dilate and regain strength.
