Abstract
When the bank of a reservoir slope slides along a weak structural plane at a high speed, “landslide slamming” will occur in the nearby water. The formation of landslide-induced waves is a serious threat to the safety of wharfs, shore marks, buildings in the water, and vessels navigating in reservoir areas. To ensure the safety of navigating ships, this study proposes a landslide-induced wave water ship navigation safety risk response technology. The propagation characteristics of landslide-induced waves are analysed based on a physical model experiment, and the characteristics of a ship's motion response and mooring cable tensions are studied under conditions of bow and stern mooring and multipoint mooring. The influences of the landslide-induced wave direction and ship navigation position on the ship rolling motion characteristics are discussed. The results of this study can further improve the navigation safety of ships in landslide-induced wave waters.
Highlights
When the bank of a reservoir slope along a weak structural plane slides at a high speed, the energy exchange between the landslide and water will lead to landslide-induced waves
Other studies have delved into the effects of test variables on landslide-induced waves, such as the still water depth, slide impact velocity, slide thickness, bulk slide volume, bulk slide density, slide impact angle, and grain diameter [4]. e same experts studied the characteristics of landslide-induced waves using physical model tests
A physical model experiment to test such a procedure was conducted. e propagation characteristics of landslide-induced waves and the characteristics of a ship’s motion response are studied under conditions of bow and stern mooring and multipoint mooring. e models provide a reference for the modelling of other types of landslide-induced waves
Summary
When the bank of a reservoir slope along a weak structural plane slides at a high speed, the energy exchange between the landslide and water will lead to landslide-induced waves. Scholars have studied model tests on landslide-induced waves, ship navigation safety, and risk response technologies to a certain extent. Other studies have delved into the effects of test variables on landslide-induced waves, such as the still water depth, slide impact velocity, slide thickness, bulk slide volume, bulk slide density, slide impact angle, and grain diameter [4]. E same experts studied the characteristics of landslide-induced waves using physical model tests. McFall et al [13, 14] modelled a landslide-generated tsunami source and propagation scenarios in a three-dimensional tsunami wave basin and studied the tsunamis generated by three-dimensional deformable granular landslides on planar and conical hill slopes. Is paper proposes a response procedure to cope with the risk of ship navigation safety when subjected to landslide-induced waves. A physical model experiment to test such a procedure was conducted. e propagation characteristics of landslide-induced waves and the characteristics of a ship’s motion response are studied under conditions of bow and stern mooring and multipoint mooring. e models provide a reference for the modelling of other types of landslide-induced waves
