报告题目:The Mechanics of Debris Flow

报告摘要:

  Debris flow is a natural phenomenon that occurs in mountainous terrains. The flow process is usually initiated by slope failure at high ground followed by rapid mass movement along steep channels. Debris can grow in size due to erosion of the channel, called entrainment, and it can become smaller due to deposition along the channel as levies and depositional fans. Debris is mainly composed of soil and rock of a wide range of sizes and it can include trees, vegetation and other materials collected in its path. Water is a common element in debris and the presence of water changes its flow characteristic dramatically.

The presentation will discuss the mechanics of debris flow and various numerical techniques to calculate the velocity and extend of the flowing mass. Discussion will include entrainment and constitutive modelling for debris flow analysis.  Laboratory test and case histories are used to study the effectiveness of the models in debris flow analysis
