HIGHLIGHTS
- who: PFC et al. from the The University of Western Australia have published the Article: Effects of width-height ratio and roof-�oor strength on the mechanical characteristics of cemented gangue back�ll pier-column, in the Journal: (JOURNAL)
- what: The end friction constraint is the main reason for the width-height ratio effect and the higher the friction coefficient is the larger the width-height ratio effect shows and the width-height ratio effect disappears without end friction constraint. One of the main purposes of CGBP design is to determine the optimum geometry of . . .
