Abstract: Based on the simulation method of crack peeling propagation failure process, a prediction method for critical load was proposed, and an equivalent critical vacuum pressure load control line and design criteria for preventing interfacial crack peeling and propagation failure were constructed by means of the critical strain energy release rate and damage initiation stress of the lining interface. The results indicated that the critical pressure load was controlled by the initial pre-crack length, critical strain energy release rate and initial damage stress at the composite interface. It was negatively correlated with the initial pre-crack length, but positively correlated with the critical strain energy release rate (GIC) and the initial damage stress (T0). When the initial pre-crack length increased from 11.11 % to 15.55 %, the critical pressure load (Pc) decreased by 34.9 % from 87.6 kPa to 57 kPa. The coordinate points of interface peeling toughness parameters (T0, GIC) were located above the control line of equivalent critical vacuum pressure load, which could effectively prevent the failure of lining interfacial crack peeling and propagation.
