Experimental study on seepage erosion based on transparent soil and particle tracing technology

Yantu gongcheng xuebao, 2022
Seepage erosion is one of the main reasons for the instability and failure of hydraulic engineering. In the process of seepage erosion, the fine particles of the soil are gradually lost, and the permeability of the soil is enhanced, which further affects
