  4. 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。
  5. The incident wave height h1 / 3 is in the range from 0. 1m to 0. 25m, and the peak period tp in the range from 1. 0s to 2. 0s. the ratio of s / h1 / 3, which refers to the subface level of wharf deck ( s ) to the incident wave height ( h1 / 3 ), is between - 0. 1 and 0. 7. three different shore connecting types : open - piled, permeable slope with armored 1ayer of dolosse b locks and impermeable slope with armored layer of concrete plate, are set in the experiment for the research on the effects of boundary condition with different shore connecting types on the wave impact

    本文的物理模型試驗在大連理工大學海岸和近海工程國家重點實驗室的大波流水槽中進行，試驗中選用的隨機波靶譜為改進的jonswap譜，入射波波高h _ （ 1 / 3 ）范圍為0 . 1m 0 . 25m ，譜峰周期t _ p范圍為1 . 0s 2 . 0s ，碼頭面板的相對凈空（碼頭面板底面距離靜水面的距離s與入射波波高h _ （ 1 / 3 ）的比值）范圍為- 0 . 1 0 . 7 ，其中s / h _ （ 1 / 3 ）為負值時表示碼頭面板底面位於靜水面以下。
