我国《民法典》第三百八十八条明确认可“其他具有担保功能的合同”效力,但并未具体规定动产和权利担保统一登记制度。《国务院关于实施动产和权利担保统一登记的决定》首次提出将部分动产和权利担保纳入统一登记,并最终以《动产和权利担保统一登记办法》作为统一登记制度的具体规范,替代原《应收账款质押登记办法》。由于动产和权利担保登记制度中所涉各类担保权利存在不同的登记效果,并且其对相应担保权利的实现具有效果相异的影响,因而需要注意登记相关实务事项。动产和权利担保登记制度不直接产生传统担保登记的效力,其更类似于发挥权利公示“留言板”之作用。

Flat geotubes are widely used for coastal structures such as seawalls, breakwaters and sightseeing groins, etc.. However, the understanding of the stable mechanism involved in the wave-structure interactions should be deepened, and one of the important work is to clarify the stress state of the structure under the wave action. In this article, wave force acting on coastal structures made of flat geotube is experimentally investigated. The required drag, inertia and lift coefficients are especially analyzed from the results of hydraulic model experiments specially designed for geotube structure. Several types of structures made of flat geotubes under wave action have been tested in order to understand the stress state of the geotube fixed to force transducer within different structures. Experimental results show that the wave-induced forces on the instrumented geotube are markedly influenced by wave elements. Meanwhile, the magnitude of horizontal force of adjoining geotube is different at the same time.
