Study on the Steepness of Landslide-Induced Wave and Nonlinear Motion of Container Ships

Abstract

Large-scale instability of a landslide body, sliding down a bank slope and entering water at a high speed, arouses landslide surges. Taking the water entry point as a source point, they spread rapidly to surrounding areas, increasing the danger risk of vessel passages in the water area. In this paper, adopting an orthogonal experimental design method, based on the test data, the Three Gorges Reservoir area was derived in order to calculate the height of the first wave of the bank landslide surge: to analyze the slope angle, the geological environment, the volume of the landslide surge, and the landslide surge wave steepness; to study the landslide volume effect on ship rolling and the swaying motion rule; and to explore the landslide surge in different ship rolling positions and transverse oscillation characteristics. This study can provide theoretical support for the navigation safety of ships in landslide surge waters.

Innovative Method for Ship Navigation Safety Risk Response in Landslide‐Induced Wave

“…According to a preliminary investigation conducted by a research group [17], landslides can easily occur from 20°to 60°on the bank slope of the Wanzhou section of the ree Gorges Reservoir. rough a mathematical statistical analysis [18], it was determined that when a landslide occurs, the average dip angle is 36°. Combined with the experimental conditions and theoretical analysis results [18], in this study, when the dip angle was 40°, the high-energy invert efficiency between the landslide body and water body and maximum water level value of the landslide-induced wave changed.…”
