Abstract: The wood physical and mechanical properties of 5.5a Eucalyptus grandis from Sichuan Introduction plantation were analyzed. The results show that 5.5a Eucalyptus grandis wood is of lightness, small deformation. The air dry density is 0.498 g/cm³, the over-dry density is 0.474 g/cm³, the basic density is 0.405 g/cm³ and the shrinkage coefficient of the volume is 0.487. The compressive strength parallel to grain is 47.97 MPa, the bending strength is 90.60 Mpa, the bending elastic modelus is 10411 MPa and the toughness is 60.8 KJ/m²;The composite strength is 138.57 MPa, and belongs to middle level.

Key words: Eucalyptus grandis, plantation, wood physical property, wood mechanical property
