Journal of Marine Science and Technology

In general, the activities of harbour district, coastal construction and re-transportation of tide and current are all possible to influence the stability of research area and sediment environment in nearshore area. It indicates that status of deposit property of seabed and variability of sediment environment are important factors to stability and safety for the path of undersea gas pipeline. An assessment procedure and approach for the prediction of the wave-induced and earthquake-induced liquefaction potential and erosion potential are proposed for marine engineering practice. The soil sample of this study is obtained from deposit zone of gas pipeline of seabed in …
