摘要:
植被发育斜坡土体中广泛存在由各种大孔隙组成的大孔隙网络系统,其分布特征影响斜坡水文行为和孔隙水压力场,对斜坡稳定性有重要影响。运用亚甲基蓝溶液分别在木本植被群落斜坡和草本植被群落斜坡土体进行染色示踪渗透试验。通过对垂直剖面大孔隙分布模式的分析和对整个试验区大孔隙的深度分布的统计分析,研究大孔隙分布的非均匀特征。研究结果表明:1.大孔隙在垂直方向和横坡方向上的分布都表现出非均匀性,顺坡方向表现出明显的变异性;2.大孔隙分布表现出显著的各向异性特征,横坡方向的非均匀性比顺坡方向的非均匀性显著;3.草本植被群落斜坡土体大孔隙分布的非均匀性和变异性比木本植被群落斜坡显著;4.在100 cm×100cm...
Abstract:
Macropore network systems exist extensively in soil of well vegetated slopes. The distribution pattern of macropores influences the hydrologic behavior of and the pore water pressure field of well vegetated slopes, and macropores have great adverse impact on slope stability. Aqueous solution of methylene blue was chose and dye trace infiltration experiments were carried out in woody plant community slope and in herbaceous community slope, respectively. The heterogeneous characteristics of macropores distributions were analyzed using statistical method based on the dye stained profiles. The results show that：1)the distribution of macropores exhibited distinct heterogeneity in vertical direction and in transverse direction, while the distribution of macropores exhibited distinct variability in vergence direction；2)the distribution of macropores exhibited distinct anisotropy, the heterogeneity in transverse direction was more significant than in vergence direction；3)the heterogeneity of and the variability of the distribution of macropores were higher for herbaceous community slope than for woody plant community slope；4)it was reasonable to study the distribution characteristics of macropores at 100 cm×100 cm scale.
