Dynamics Analysis of Niujuangou Rockslide-Debris Avalanche Triggered by the Wenchuan Earthquake

Abstract

Abstract: Niujuangou rockslide-debris avalanche is known as a typical rockslide-debris avalanche, which was triggered by the Wenchuan earthquake. Superposed earthquake effects came from horizontal and vertical directions made initial rock mass throw out and move rapidly, after experiencing several strikes, rock mass almost fragment, and sliding mass move like debris avalanche in Niujuangou creek. A dynamic model DAN was used to back analysis of this event. Both Friction rule and Voellmy rule were modeled and compared. The results show that it would be best to adopt Friction rule in the proximal path and Veollmy rule in the distal path. And most suitable parameters, volume and profile of deposition, velocity of sliding mass were obtained.

Key words: Niujuangou rockslide-debris avalanche, numerical simulation, dynamic analysis
