中文摘要:对粘性土中孔隙水运动规律具有若干种不同认识,用传统粘性土结合水运移的理论无法作统一的解释,妨碍了该领域许多理论和实践问题的解决。本文对粘性土孔水渗透规律提出了不同于传统结合水运移理论的新认识,认为粘性土饱水时,存在重力水、毛细水和结合水,水在土中渗透运动是不同的水力梯度条件下3种孔隙水相互转化、综合作用的结果,而参与运动的孔隙水的释出规律,决定了粘性土孔隙水不同的渗透规律。 |

New Understanding of the Regularity of Water Seepage in Cohesive Soil |

Abstract:There exist different viewpoints in literature and reference materials concerning pore water movement in cohesive soil, and traditional theories have failed to make reasonable explanations. As a result, some theoretical and practical problems in this field have not yet been solved. The authors put forward a new viewpoint on the basis of many researches and permeability tests in saturated cohesive soil, holding that the movement regularity of water seepage results from the mutual transformation of bound water, capillary water and gravitational water under different hydraulic gradients. Therefore the releasing law of gravitation water governs the diffe-rent pore water seepage regularities in cohesive soil. |
