| 摘 要： | 通过自制的试验装置,模拟天然降雨过程,研究碎石土斜坡优先流的形成机理以及优先流对碎石土斜坡地下径流的影响,为揭示降雨诱发碎石土斜坡变形破坏机理提供理论依据和数据支撑。研究了颗粒组成结构、降雨历程、地下水、干缩、冻融交替等因素对碎石土斜坡优先流的影响,以及优先流对碎石土颗粒组成结构、碎石土斜坡地下径流的影响,揭示碎石土斜坡优先流的形成机理。通过染色示踪试验,揭示了碎石土斜坡优先流的形态和分布特征,为碎石土斜坡优先流的进一步量化研究提供依据。

| Abstract: | Based on a self-made testing equipment,the rainfall process is simulated.The gravel slope flow priority and the formation mechanism of preferential flow are studied.The results reveal the rain-induced gravel slope deformation and failure mechanisms and provide the theoretical basis and data support.The impact factors of soil components,history of rainfall,groundwater,drying,freezing and thawing are analyzed.Through tracer dye test,the gravel slope of preferential flow patterns and distribution for the grave... |
