The Application of failure criterion of frozen soil based on fracture mechanics in hydraulic engineering

This paper established a failure criterion of frozen soil based on fracture mechanics considering various defects and destruction mechanism of frozen soil. The criterion fits for frozen soil under small scale yielding conditions or brittle fracture. It indicates that the failure criterion is valid by applying to the actual anti-frozen research of hydraulic structures destruction. It provides a new idea for the research on the anti-frozen damage to hydraulic structures in seasonal frozen soil area.
