Abstract

Hydraulic fracturing is of great concern in earth-rock dam engineering and is also one of the hot research issues in earth core dams. Hydraulic fracturing can cause the destruction of the dam's anti-seepage body and cause catastrophic consequences. This paper uses a triaxial hydraulic splitting test to quantitatively describe the shape of hydraulic fractures in clay core, and further demonstrates the occurrence mechanism of hydraulic fracturing from a microscopic perspective. Hydraulic fracturing is ultimately a deformation problem. Due to the compressive deformation of the soil, the initial fracture takes an elliptical shape in the two-dimensional space, thus producing a wedge splitting effect on the fracture tip.
