tidal scour

Because the pipeline diameter in platform is one third of that in tidal channel, so the limit scour length is less.

而平台区由于设计管径仅为潮汐通道区的三分之一，其极限冲刷长度远小于潮汐通道区。

Therefore, the seabed soil failure due to the tidal current scour in the cable route area may occur to affect the safety of submarine cable buried in the seabed soil.

路由区海底土会因潮流冲刷作用而发生失稳破坏，影响埋设在海底土中海缆的安全。

The numerical models of tidal currents and sediment transport for three generalized physical models are established. From the numerical models, the effects of distortion ratios on tidal currents and sediment scour and silt in the channel are given.

采用数学模型进行模型变率影响研究，针对系列概化物理模型建立了相应的潮流数学模型和泥沙数学模型，给出了模型变率对潮流流速和航道冲淤变化的影响。

潮流作用下桥墩局部冲刷研究

There are six types of the underwater dynamic morphology in Fangcheng Bay: intertidal shoal, tidal current scour, underwater entrance bar, underwater sandy mouth, underwater slope, submarine plain.

其中，水下动力地貌有6种类型：潮间浅滩、潮流冲刷深槽、水下拦门沙坝、水下沙嘴、水下岸坡、海底平原。
