These tests show that: 1. suction decreases with the increase of the water saturation in the chalk; 2. stress variants proposed are available for describing the stress state of the unsaturated chalk; 3. preconsolidation pressure increases with suction, while the effects of suction on the compressibility coefficients λ and κ are not evident; 4. as usual unsaturated soils, the permeability to oil of chalk increases with the suction; 5. yield strength of the chalk behaves with volumetric strain hardening; 6. cohesive behaviour of the chalk is related to the stress level, and relation between time-dependent deformation and logt is linear; 7. cohesion of the chalk decreases with the increase of the suction, while the elastic stiffness and the cohesion coefficient increase; 8. strength and elastic modulus increase with the strain rate, while the strain at the peak strength decreases with the increase of the strain rate.

试验结果表明，白垩中的虹吸力随水饱和度的降低而提高；吸力、水饱和度和强度的变化过程均与时间有关；可用由理论分析得到的应力状态变量描述非饱和白垩的平衡状态；前期固结压力随吸力增加而提高，而压缩指数λ与κ则同吸力无关；应力大于前期固结压力时，粘性变形与时间的对数关系曲线呈线性关系，其大小和增长速率均随吸力减小而增大，可视为白垩弹性刚度降低和粘性系数增大的结果；前期固结压力和变形模量随着应变速率的提高而提高，压缩指数κ和λ则随应变速率的提高而减小；应变速率较低时，粘性和吸力对前期固结压力及压缩指数的影响较小；白垩中油的渗透性随着吸力增加而提高；白垩在屈服阶段具有明显的体积应变硬化特性。
