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。

Teacher, Shen mentioned formula replicability reasoning using mathematical methods, often with red, yellow and blue chalk in turn show the hands of this teacher, Shen, colored chalk, such as beating of the notes, images, vivid, so that we are both relaxed and learn together happy; Shen teacher also used chalk powder into the suspension liquid foam, and emulsion, the solution can be compared; to chalk on the throw, drop to indicate what is the role of inertial motion and gravity; is to compare chalk down chalk placed on the desktop Pressure Size ......

沈老师讲到公式的举一反三，在用数学方法进行推理时，往往用红、黄、蓝粉笔依次展示，沈老师手中这彩色粉笔如跳动的音符，形象、生动，使我们学起来感到既轻松又愉快；沈老师还用粉笔灰泡成悬浊液，与乳浊液、溶液进行比较；将粉笔上抛、下落来说明什么是惯性运动和重力作用；正倒放置粉笔来比较粉笔对桌面压强的大小……总之，每一节每一课，沈老师的粉笔都有妙用。
