摘要
通过试验模拟天然降雨条件,研究了碎石土颗粒组成结构、地下水径流、温度、干缩冻融交替等因素对碎石土斜坡优先流的影响;采用染色示踪法揭示了碎石土斜坡优先流的形态和分布特征,为揭示碎石土斜坡变形破坏机理提供理论支撑,并为地下工程的施工提供指导。
Through experimently simulated natural rainfall, the effect of the structure of debris composition strue ture, underground runoff, temperature, shrinkage freeze-thow alternating on debris slope preferential flow is studied. The gravel slope morphology and distribution characteristic of preferential flow is revealed by dye tracer test. It provides theoretical support for revealing debris slop deformation mechanism and provides a basis for further research.
