The invention provides a hull strengthening method of a launching barge. The ship body strengthening method comprises the following steps that the position of a launching slide way is determined according to the weight gravity center and the main scale of a to-be-launched structure and the position of a bulkhead or a strong structure of a ship body, and a launching arrangement diagram is formed; according to the launching arrangement diagram, the structure diagram of the launching barge, the structure diagram of the to-be-launched structure and the structure diagram of the launching slideway, a finite element model is established, and finite element calculation is carried out after the gravity center of the weight and the boundary are leveled; determining a to-be-reinforced area which does not meet the requirement of the structural strength and needs to be reinforced on the ship body by combining the calculation result of the finite element and the requirement of the specification; identifying a reason causing that the structural strength of the to-be-reinforced area does not meet the requirement; and when the reason for the insufficient structural strength is insufficient shear strength, the flitch is attached to the to-be-reinforced area and clamped to the structural plate of the ship body.

    本发明提供了一种下水驳船的船体加强方法。船体加强方法包括以下步骤:依据所述待下水结构的重量重心、主尺度以及所述船体的舱壁或强结构的位置,确定所述下水滑道的位置,并形成下水布置图;依据所述下水布置图、所述下水驳船的结构图、所述待下水结构的结构图以及所述下水滑道的结构图创建有限元模型,并调平重量重心及施加边界后进行有限元计算;结合上述有限元的计算结果以及规范的要求,确定所述船体上结构强度不满足要求而需加强的待加强区域;识别导致上述待加强区域的结构强度不满足要求的原因;在结构强度不足的原因是剪切强度不足时,在所述待加强区域处将贴板贴合并夹紧于所述船体的结构板处。
