摘    要:通过试验模拟研究了预制混凝土连锁块在洪水期水流中的受力状况、整体稳定性、孔内填充碎石的作用及连锁块阻力参数,综合分析了连锁块结构的力学稳定性和抗冲性;给出了碎石填充的要求及安全度。试验表明:新型生态防洪工程护面连锁块与传统堤防工程的护面形式相比,具有抗高切应力、稳定、透水性好、改善河道生态环境等优点,而且施工方便快捷。

关 键 词:生态防洪工程  连锁块  脉动压力  抗冲性  糙率

Abstract:The stress condition ; overall stability ; effect of filling gravels into the hole of the block of the precast concrete interlocking blocks in the water flow during the flood period as well as the resistance parameters of the blocks are studied through experimental simulation; in which a comprehensive analysis is made on the mechanical stability and the anti-erosion properties of the blocks, and then the requirement and the safety degree of the gravel filling are given. The experiment shows that compared with the surface protections of the conventional dyke projects, this new type of the surface protection has the merits of higher resistance to high shear tress; better stability and permeability and has the advantages to improve the eco-environment and facilitate the construction concerned.
Keywords:ecologiocal flood-control project  concrete interlocking blocks  fluctuating pressure  anti-erosion properties  roughness
