The invention discloses crack-resistant glued laminated bamboo, which comprises a first bamboo blank layer (1) placed longitudinally, a second bamboo blank layer (2) placed obliquely at a certain angle and a third bamboo blank layer placed longitudinally (3). The first bamboo blank layer (1), the second bamboo blank layer (2) and the third bamboo blank layer (3) placed longitudinally are bonded and hot-pressed to form a whole. The crack-resistant glued laminated bamboo has the advantages of increasing tensile force of transverse fibers between the adjacent bamboo blank layers and preventing the bamboo blank layers from cracking.
