非饱和土力学实用化之路探索

Exploitation of practical use of unsaturated soil mechanics

    摘要
  • 摘要: 非饱和土力学的研究水平目前还停留在学院式阶段,主要原因在于吸力量测的困难。为了促进非饱和土力学的实用化,在分析吸力的3种作用机制的基础上提出了几种吸力的替代方案,如饱和度、折减吸力和广义吸力。此外,孔隙气压力的计算也是一件麻烦事,为此提出了简化计算方法。最后探讨了非饱和土中表面裂缝的形成对边坡稳定和变形的影响。

     

    Abstract: Until now the research activities in the field of unsaturated soils have been still in the academic stage.The key point of troubles is the measurement of suction.Three possible ways to use degree of saturation,reduced suction or generalized suction instead of matrix suction were proposed.In addition,a simplified consolidation theory of unsaturated soils about pore air pressure was advanced.The influence of cracks in clay surface on the stabilization and deformation of slope was discussed.
