Abstract EN
The collapsed body formed after the underground power disaster is broken into loose body.
The mechanical characteristics of the collapsed body are quite different from those of the homogeneous rock mass, and the rescue tunnel is affected by its moving characteristics.
In this study, the lateral pressure coefficient of the collapsed body and the angle of the slip surface were deduced.
The numerical experiment based on CDEM slump excavation was performed.
The accumulation state of the collapsed body and the active lateral pressure coefficient and the angle of the slip surface are obtained.
The characteristics of the force of the accumulation body which naturally collapsed were studied.
Particle size, excavation position, excavation shape, volume, and the influence of natural repose angle on the occurrence mode and particle movement were obtained; the velocity field and slip surface of the lower left and middle lower parts during excavation and the variation of the natural repose angle were analyzed.
