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 physical experiments and theories on thermodynamics prove that gas thermal insulation coefficient changes apparently when hydraulic transition process happens. so four appropriate processes were given - sub - process 1 of compressing, sub - process 2 of inflating, sub - process 3 of inflating, sub - process 4 of compressing
試驗與理論分析表明，在管道系統發生水力過渡過程時氣體多方指數n存在較為顯著的變化，並非單一常數，從而提出了相應的四過程：即壓縮子過程1 、膨脹子過程2 、膨脹子過程3和壓縮子過程4 。
