excess rainfall 解釋
超滲雨量
  • excess : n 1 過量；過剩。2 超過，超越。3 超過數量。4 過度，（飲食等）無節制。5 〈pl 〉 過分行為，暴行。adj...
  • rainfall : 下雨，雨量。
  1. When soil antecedent condition is dry and the initial rainfall intensity is high, peak surface runoff also considerably lag behind that of rainfall, because of the formation of temporary relative impermeable top layer ; b ) surface runoff is controlled primarily by infiltration - excess runoff mechanism under unsaturated condition ; the major fraction of surface runoff are dominated by saturated infiltration - excess runoff response, only a small fraction by return flow mechanism when soil is saturated ; c ) subsurface flow is dominated by saturated runoff mechanism, and the duration of subsurface post the rainfall end is dependent upon rather the soil properties than the rainfall characteristics ; d ) subsurface flow intensity in cultivated soil layer ( 0 ~ 20cm ) is high up to 35mm / h when rainfall intensity is up to 120mm / h, indicating the existing of macropores and pipe flow in cultivated layer

    2 ）耕作制下紫色土的產流主要機制是： 1 ）當雨前土壤含水量未達到飽和狀態時，表面產流起始時間有明顯滯后現象，這與紫色土的快吸水性和較多非毛管孔隙密切相關；當雨前土壤較乾燥，降雨初期雨強較大時，易形成臨時相對不透水表層，表面產流峰也有明顯滯后現象。 2 ）表面徑流的產流方式主要是超滲產流，當土壤達到飽和狀態后，有四川大學博士學位論文小部分回歸流發生，但主要是飽和超滲產流發生，因為紫色土的相對不透水層和其它透水障礙層不明顯。 3 ）壤中流主要是飽和產流，與降雨過程有明顯的滯后，而且雨停后的壤中流產流歷時與降雨特徵無關。
  2. The reason for the failure of loosely residual soil slopes triggered by rainfall is that the contractive failure caused by the penetration of rainfall, giving rise to a high excess pore pressure which reduces shear strength of the soil. the soil is prone to flow slide after failure under the action of gravity due to its high moistu re content

    蔣家溝地區坡殘積土斜坡在暴雨條件下的破壞是由於降雨入滲導致土體發生剪縮破壞，破壞後土體的孔隙水壓力升高形成超孔隙水壓力、土體強度降低、破壞迅速擴展所致，因而大多數斜坡呈流滑型破壞並具有突然性破壞特點。
  3. During 1990 ' s, the impacts of human activities excess that of rainfall

    90年代人類影響已超出降水等氣象因素的一面。
