At the same time, the quality of different - state water was studied. the results show : the soil bulk density of the fir wildwood heightens with the increase of soil depth, specifically 0. 74 > 0. 94 andl. 34g / cm3, the saturated, canaliculus and field moisture contents decrease gradually in layer a, b and c, accordingly the soil total foveola decreases gradually, and the moisture - hold capacity of the soil lessens gradually with the increase of the soil depth ; there is small difference of the soil bulk density between layer a and b in the outer space, which are respectively 0. 92 and 0. 99g / cm3, and the other laws are the same as the in ner in the main ; reverse success often occurs in the low position of the thoroughly - fell trace and plateau marsh is formed
結果表明:冷杉原始森林土壤容重隨土層深度的增加而增大,分別為0 . 74 、 0 . 94 、 1 . 34g cm ~ 3 ,飽和持水量、毛管持水量、田間持水量a層、 b層、 c層逐漸減小,十壤總孔隙度也逐漸減小,土壤的持水能力隨深度的增加逐漸減弱;林外空地a層、 b層十壤容重相差不人,分別為0 . 92和0 . 99g cm ~ 3 ,其它規律與林內人體相同:皆伐跡地的低洼地段容易發生逆行演替,形成高原沼澤地。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。Based on the results of these tests, strength model and pore water pressure model have been advanced and validated. in addition, not only have the liquefaction mechanism of the soils been analysed, but also the influence of the factors on the extent of liquefaction of the saturated soils have been discussed
在總結前人工作的基礎上,結合本次試驗成果,分析了飽和土體的液化機理及其影響因素,主要討論了土性條件(包括試樣密度、顆粒特性、固結時間、超固結及其結構性)和初始有效固結壓力的影響。( 2 ) the emitter discharge of simple subsurface drip irrigation is greater than the infiltration rate after formed saturate loop in the short time. infiltration rate under subsurface drip irrigation is not only affected by soil texture, original soil moisture content and soil bulk density et al, but also by emitter discharge, which affect by water pressure
( 2 )地下滴灌的灌水器出流量一般在較短時間內形成飽和圈后,土壤入滲速率不僅受到土壤質地、土壤初始含水率、土壤容重等因素的制約,而且還與影響灌水器出流速率的壓力水頭有關。分享友人
