AI Technical Summary
Existing technologies fail to consider the deterioration effect of layer vibration when analyzing the seismic stability of underground caverns in layered rock masses, resulting in inaccurate seismic stability evaluation results for underground caverns in rock masses.
An elastoplastic deterioration constitutive model for layered rock mass is constructed, taking into account the deterioration effect of bedding vibration. By clarifying the transverse isotropic elastic mechanical behavior of layered rock mass, the strength criterion of layered rock mass and plastic potential function, the bedding failure index is defined, the seismic stability safety coefficient of underground caverns in rock mass is calculated, and the seismic stability safety range is determined.
It improves the accuracy and safety of seismic stability assessment of underground caverns in rock masses, provides a more reliable range of seismic stability safety for underground caverns in rock masses, and enables a better understanding of the seismic response patterns of layered rock mass caverns.
