Outline of Annual Research Achievements |
In this project, an experimental apparatus is designed to simulate the relative motion between the submarine landslide and undersea communication cable, and investigate the impact behavior of a submarine landslide. Based on the test data, the distributed load exerting on a cable under different velocity is analyzed. The results shows that 1) submarine landslide with larger particle size and larger thickness could generate larger impact force; 2) the evolution of the impact force with the velocity could be divided into three stages. It increased and reached a peak value at the first stage, and then decreased to a minimum value at the second stage. After that, it increased again when increasing the velocity continuously.
