Comparative study on control effect of deep roadway under full-length prestressed bolt-grouting support

This study proposed the numerical simulation method of full-length prestressed anchor grouting support based on the post-grouting technology, and the modification of the embedded PILE structural unit in FLAC3D software. Specifically, we conducted the numerical simulation and made comparison in terms...
