The reliability of analysis result depends largely on the in-house experimental conditions. Unlike the previous analysis that only concerns the sole effect of permeable pressure, this article considers both permeable and confining pressure and deformation characteristics of concrete material under the interaction of them according to the real work state of construction, which may leads to the changing pattern of permeable rate as listed below: permeable rate always reaches its peak with the time process going on, than goes down and remains straight on some certain value; The PR will tend to decline while the confining pressure is increased, and the time taken before the peak will be extended as well; Under the constant permeable pressure and circularly changing confining pressure, the minus-exponential ascend and descend relationship could be applied between the PR and Time axes respectively with crannied and intact concrete samples, and the PR of crannied concrete is far more larger than that of intact concrete. The change pattern of concrete could also be mathematically analogized using the least square method.
室内的实验条件是研究成果可靠性的重要因素,而以往的研究都只考虑了渗透压单一作用,本文根据混凝土结构的实际工作状态,同时考虑了围压与渗透压共同作用下的混凝土材料的渗透性变化特征,得出了混凝土材料在围压作用与渗透压共同作用下的渗透率的变化规律:渗透率都是随时间推移先达到一个峰值,再降低并趋于平稳;渗透率会随围压的增大而减小,并且峰值的到达时间也会随之延长;在渗透压不变,围压升降循环的情况下,有裂缝、无裂缝混凝土的渗透率变化规律是随时间成负指数关系上升、下降,且有裂缝混凝土试件的渗透率远远高于无裂缝混凝土的渗透率,并对混凝土的变化规律运用最小二乘法进行数学拟合。

Before fissuration, osmotic adjustment occurred by the addition of solute to cells and decreasing the loss of water in the body, so that it could maintain normal turgor pressure during drought. After fissurate growth, turgor pressure was maintained by higher cell and tissue elasticity lower ε(superscript max and by osmotic adjustment for normal plant development in dry conditions and to avoid dehydration under water stress during the drought period, but it also became more sensitive to water stress. The ability to maintain turgor pressure varied from strong to weak during the period before, during and after fissuration. Fissurate growth decreased the ability of P. mongolica to maintain turgor pressure and led to changes in walls related to drought tolerance.
结果表明:1未劈裂绵刺主要通过增加细胞内溶质,减少细胞内的水分丧失来进行渗透调节,从而在干旱胁迫下能够维持正常的膨压。2己劈裂绵刺通过渗透调节和高的组织弹性两条途径来共同保持膨压,以抵抗不良的生存环境;同时对环境水分胁迫具有较高的敏感性。33种状态绵刺保持膨压的能力由强到弱依次为:未劈裂绵刺、正在劈裂绵刺、已劈裂绵刺。4劈裂的发生导致绵刺保持膨压能力的降低,同时耐旱方式和途径发生了变化。
