混凝土联锁块软体排受波浪作用的结构稳定性

Structural stability of soft mattress of concrete interlocking block under wave action

对波浪作用下的混凝土联锁块软体排结构进行了受力分析。通过分析可知:波浪的作用使软体排四周产生水压差,当该压差作用形成的波浪力矩大于软体排的稳定力矩时,软体排结构失稳。并建立软体排受波浪力作用的数学模型,开展了混凝土联锁块软体排结构稳定性研究。基于上述分析,提出一种卸压型压载块结构进行数模研究。数模结果表明,卸压型压载块结构可通过卸压孔减小压载块所受到的波压差来减小波浪力矩,提高压载块的稳定性。

The force analysis of the soft mattress of concrete interlocking blocks under wave action is carried out.It can be seen from the analysis that the effect of the water pressure difference around the soft mattress is caused by the wave action.When the torque of the wave formed by the pressure difference is greater than the stable torque of the soft mattress,the structure of the soft mattress is unstable.The mathematical model of the soft mattress subjected to wave force is established,and the structural stability of the concrete interlocking block soft mattress is studied.Based on the above analysis,a kind of unpressurized ballast block structure is proposed for numerical simulation.The numerical simulation results show that the wave moment can be reduced and the stability of the new structure can be improved by reducing the wave pressure difference of the structure through pressure relief hole.
