Modeling Soil Disturbance Due to Tillage and Traffic,elines can be used to advantage. From the brief description of two soil compaction models, it is concluded that models are of most value in ranking the effects of various wheel geometries and arrangements, and in investigating the sensitivity of the wheel and soil input variables.作者: ABIDE 時間: 2025-3-22 01:33 作者: 呼吸 時間: 2025-3-22 04:38

Modeling Soil Mechanical Behavior During Compaction,ue to plastic deformation is not accurately accounted for in existing soil compaction models. This limitation may be important in the prediction of compaction caused by wheels in tilled soils. Research needs for more accurate yet simple compaction models and better representation of soil mechanics processes during compaction are outlined.作者: HALL 時間: 2025-3-22 20:49

Effects of Dynamic and Static Loading on Compaction of Structured Soils,ing. But even at short loading times soil strength is increased in soils with low hydraulic conductivity as well as in structured soils. Soil strength was predicted by multiple regression analysis. Precision of the prediction was increased significantly by including shearing-resistance parameters as independent variables.作者: CLAMP 時間: 2025-3-23 15:56 作者: 盡忠 時間: 2025-3-23 18:13
Strength of Low and Variable Charge Soils,end on complex interactions among charges, exchangeable cations, and moisture. The role of specific ions and of certain organic matter fractions has yet to be ascertained. Recognition of the mechanisms controlling strength variation, especially within soils, has important implications for the physical management of these soils.作者: 擔(dān)心 時間: 2025-3-24 01:10 作者: 莎草 時間: 2025-3-24 04:13 作者: 脖子 時間: 2025-3-24 10:28 作者: cortisol 時間: 2025-3-24 12:23

Root System Responses to Soil Structural Properties: Micro- and Macro-Scale,ods suggests that purely mechanical processes cannot account for all the reactions of roots. Models based on balance of pressures on root tips have, therefore, several points of weakness which are discussed.
