In this paper, the influence of cycles of drying and wetting on strength and deformation are studied by means of routine direct shear apparatus, triaxial apparatus and light consolidation apparatus which include : the influence of force of constraint on strength, the total stress strength of expansive soils with different saturation degree, the influence of cycles of drying and wetting on the total stress strength, the relation between saturation degree and compression modulus and that between saturation degree and void ratio, the influence of cycles of drying and wetting on the effective stress strength, the relation between saturation degree and generalized suction
本文利用常規直剪儀、三軸儀以及輕便固結儀，分別對非飽和膨脹土的強度和變形特性以及干濕循環對強度和變形的影響進行了一系列的試驗研究。以飽和度、干濕循環次數為變量，分別探求了外力約束對膨脹土強度的影響，不同飽和度膨脹土的總應力強度特性，干濕循環對非飽和膨脹土總應力強度的影響，飽和度與壓縮模量以及孔隙比的關系，干濕循環對飽和膨脹土有效應力強度指標的影響，廣義吸力與飽和度的關系，建議了一組計算非飽和膨脹土變形及強度特性的經驗公式。 -
The feasibility and availability were studied by comparing the static tests and the effects of relative stir - elastic - module that the concrete in long - term immersion and drying and wetting cycle in saturated sodium sulfate solution
結果表明，相對動彈性模量表徵的抗鹽結晶侵蝕系數與相對抗折強度及劈拉強度表徵的抗鹽結晶侵性系數評價指標具有較好的相似性。 -
Test method for wetting and drying test of solid wastes
固體廢棄物的浸濕和烘乾的試驗方法 -
The first time of drying and wetting cycle gave the most influence to total quantity of fixed potassium, and with cycles increasing, it ' s influence became weaker
隨著干濕交替次數增加，土壤對鉀的固定量增大，且增加幅度逐漸趨于穩定。干濕交替次數與土壤速效鉀含量間具有y = a + blogx函數關系。 -
Finally, two examples were used to analyse the influence of cycles of drying and wetting on subgrade sedimentation and slope stability of expansive soils, the conclusion is given that the influence of cycles of drying and wetting on strength and deformation must be considered to the foundation or structures which consists of expansive soils
最後我們採用兩個算例分別計算了干濕循環對非飽和膨脹土路基沉降以及邊坡穩定的影響，通過計算得出了在以非飽和膨脹土作為構築物基礎或構築物時，應認真考慮干濕循環對其強度和變形特性降低的影響的結論。 -
In view of improving the efficiency of fertilizer, we paid more attention to the effect of water dynamic process and strength on nutrient availability. in this research, by model test, four kinds of agricultural soils were studied, concerning about the effect of drying - wetting alternation and temperature on potassium availability, ions " diffusion in soils under different levels of water content, and the distribution coefficient of potassium between solution and soil phases
因此，本研究通過室內模擬土壤水分的動態變化，對水分變化的過程（干濕交替不斷進行）和變化強度對養分有效性的影響，不同水勢狀態下養分離子在固、液相間的分配關系，以及不同水分條件下養分的擴散遷移規律等方面進行了探討。 -
