Abstract: Due to its concealed development process and severe consequences, seepage failure poses a significant threat to hydraulic engineering projects. To investigate the strength degradation characteristics of piping soils before and after seepage failure, an internal erosion stress path triaxial apparatus was developed for geotechnical testing. Seepage failure tests and triaxial degradation tests were conducted using this apparatus, considering the influences of three critical factors: fine particle c... More
