| 摘要≠ | Terzaghi consolidation theory describes how water-saturated clay soils compress over time as excess pore water pressure dissipates and effective stress increases. Formulated by Karl Terzaghi in 1943, this foundational theory enables prediction of settlement rates for foundations on compressible soils, a critical design concern in geotechnical engineering. | The unit hydrograph (UH) is a linear transformation that converts rainfall excess into streamflow for a watershed. Introduced by Sherman in 1932, the UH assumes that rainfall-runoff response is linear and time-invariant, enabling synthesis of flood hydrographs from design storms for dam spillway design and flood risk assessment. |
