碎石含量对三峡消落带波浪侵蚀的影响

Shuitu Baochi Xuebao
目的明确碎石含量对三峡库区消落带波浪侵蚀的影响，为消落带波浪侵蚀治理提供理论依据。方法以三峡库区紫色土坡面为研究对象，设置4个碎石含量（10%、20%、30%和40%）和3种坡度（10°、20°和30°），以裸土为对照组CK，开展室内模拟波浪冲刷试验，测定水体浑浊度值、波浪侵蚀率和孔隙水压力，阐明碎石含量对坡面波浪侵蚀的影响。结果1）水体浑浊度随波浪冲刷时间的增加呈现先上升后降至波动稳定的变化趋势，含碎石试验组水体浑浊度值相比CK组减小3.64%~25.93%；2 ...

西南喀斯特区砾石对石灰土土壤孔隙及水分入渗的影响

Shuitu Baochi Xuebao
[目的] 砾石是影响土壤孔隙和水分入渗的重要因素,明确砾石通过改变哪些土壤孔隙特征进而影响水分入渗具有重要意义。[方法] 以西南喀斯特地区砾石含量高的石灰土为研究对象,采用CT扫描和室内一维土柱入渗试验,对比分析2种砾石粒径(2.0~5.0,5.0~12.5 mm)和5种砾石含量(0,10％,20％,30％,40％)条件下的土壤孔隙特征及水分入渗特性,并使用结构方程模型探究土壤孔隙特征与入渗特性之间的耦合关系。[结果] (1)含砾石土壤的大孔隙度、孔隙连通率、孔隙形状因子 ...
