| 1 | Some open problems in granular matter mechanics显示文摘Granular matter is a large assemblage of solid particles, which is fundamentally different from any other type of matters, such as solid and liquid. Most models presented for granular matter are phenomenological and are only suitable for solving engineering problems. Many fundamental mechanical problems remain open. By analyzing characteristics of internal state structure, we propose that granular matter is intrinsically multiscale, i.e. microscale of particle size, mesoscale of force chain, and macroscale of the bulk of granular matter. The correlations among difference scales would be crucial. The mesoscale force chain network is determined by both particle properties and macroscopic boundary conditions. The evolution of the force the chain network contributes to macroscopic mechanical properties of granular matter. In addition, we discuss the drawbacks in simplifying contact forces in the current models, and the difficulties in analyzing the interaction of interstitial fluid in wet granular matter. As an appropriate application of granular matter, debris flow can be studied with granular matter mechanics; meanwhile, debris flow brings more challenges which certainly motivate future studies on granular matter. | Qicheng Sun a, Guangqian Wanga, Kaiheng Hub a Department of Hydraulic Engineering, State Key Laboratory for Hydroscience and Engineering, Tsinghua University, Beijing 100084, China b Institute of Mountain Hazards and Environment, Chinese Academy of Sciences, Chengdu 610041, China | 2009 | Progress in Natural Science:Materials International2009，19，5： | 25 |
| 2 | IMPACT OF DEBRIS FLOW ON RIVER CHANNEL IN THE UPPERREACHES OF THE YANGTZE RIVER显示文摘A debris flow gully is a 'sediment highway'. Debris flow carries huge amount of sediment into river in extreme short time. which reduces discharge capacity of the river and even blocks up the river and also causes river bank erosion. | Peng CUI (1 This research is a part of key project supported by National Natural Scence Foundation (basic) (project No. 49831010). 2 Institute of Mountain hazards and Environment, Dongchuan Debris Flow Study Station.
