The invention provides a novel torpedo anchor based on bionics and a construction method thereof. The novel torpedo anchor is composed of an anchor body, an anchor rod, anchor wings, an anchor tip anda spiral extension mechanism. The anchor wings or the anchor body is additionally provided with negative poisson ratio materials, and the uplift bearing capacity of the torpedo anchor is improved byutilizing the characteristics of tension expansion and compression shrinkage of the negative poisson ratio materials; based on the sharkskin bionic principle, the surface structure of the anchor bodyis optimally designed, the water flow resistance in the installation and penetration process is reduced, and the frictional resistance between the anchor body and a seabed soil body is increased in the pull-up working state; the bionic principle of razor clam digging is used for reference, after initial penetration is completed, a working anchor chain is tensioned to be in linkage with the spiralextension mechanism, so that the anchor rod on the inside penetrates downwards, secondary penetration into the soil body is achieved, and the uplift bearing capacity and stability of the anchor body are improved.
本发明提供了一种基于仿生学的新型鱼雷锚及其施工方法,新型鱼雷锚由锚身、锚杆、锚翼、锚尖和螺旋伸缩机构组成;本发明的锚翼或锚身增设负泊松比材料,利用其受拉膨胀、受压收缩的特性以提高鱼雷锚抗拔承载力;基于鲨鱼皮仿生学原理,优化设计锚身表面结构,减少安装贯入过程中的水流阻力,上拔工作状态时增大锚身与海床土体之间的摩阻力;借鉴竹蛏掘地的仿生学原理,在初始贯入完成后通过拉紧工作锚链连动螺旋伸缩机构,使得内部锚杆向下贯入,实现二次贯入土体,提高锚体抗拔承载力和稳定性。
